In such a manner, the performance or effectiveness of the line will be adversely affected. And what follows is poor service and complaints or dissatisfaction from the end-users. So primarily, the use of these accessories help to improve the efficiency of the application, which results in better service delivery.

Classification of Pole Line Hardware

So far we’re moving on well. And in this section, the focus is to discuss the most common categories of pole line hardware in the market. Interestingly, in as much as most of these accessories fall into different categories, you’ll find that they are applied interchangeably in most occasions. Or in some cases, they’re all used together to accomplish a particular task in an overhead line structure. So let’s describe these classifications on a one by one basis;

§  Pole Line Fasteners

This category of pole line accessories refers to the group of items commonly used for mounting wooden cross arms to poles. These fasteners are also common in mounting line construction specialty materials. They come in different sizes, designs, and shapes which is vital since it helps to match the specific application. It also allows you to have open options for the particular task you want to perform.

Pole line fastener

Some of the typical configurations of pole line fasteners include rods with threads, headed bolts, bent bolts, etc. In many instances, these fasteners often have a semi-cone point and also use square nuts and galvanized to resist corrosion and rust. Examples include brace bolts, carriage bolts, hex head bolts, oval eye bolts, straight thimble eye bolts, angle thimble eye bolts, etc.

§  Insulator Hardware

This category refers to the materials whose internal electrical charges do not necessarily flow spontaneously. Precisely, they are the types of elements that only allow a restricted amount of electric current to flow through under the electric field’s influence.

Better still in layman’s language, they are types of materials that do not conduct electricity efficiently. Some would refer to them as poor conductors of heat or electricity. Pole line insulator hardware comes in different types, sizes, designs, and importantly, materials. Typical materials include porcelain, plastic, rubber, and glass, among others. Examples of pole line insulator hardware include clevises, spool bolts, line post studs, cross arm pins, and porcelain knobs among others.

§  Dead-end Hardware

This category refers to the types of pole line hardware which do not allow live current to pass through or beyond that point. Necessarily, the design of this equipment is to prevent the transmission of a current or similar element from going beyond it.

Dead end hardware

In the pole line structure, the dead-end hardware is seemingly ordinary and widely used in various applications. Of course, they also vary in size, design, shape as well as material. They’re also significant in providing the necessary amount of tension, especially in large industrial applications. Examples include clamps, insulators, hooks, pins, shackles, eyelets, rope clips, and rope thimbles, among others.

§  Tower Hardware

These refer to the types of hardware that you commonly use for holding and tightening different components of overhead line structures. Mostly, the use of tower hardware is common, especially in fixing and supporting the components at the highest point of the poles. They’re vital since they help to support even heavy parts rendering them safe and enhancing the efficiency of the overall structure.

Tower hardware

Some of the common ones include socket eyes, thimble clevis, turnbuckles, and ball clevis among others. The materials for manufacturing the tower hardware also vary, and the use of each is dependent on the specific application.

§  Drop Hardware

The drop utility pole hardware refers to the items designed for keeping your aerial installation secure and safe. They essentially hold the relevant components in an ideal position hence preventing loose connectivity that might result in danger or inefficiency.

Clamp

The aerial drop hardware comes in various forms, and some of them include wire clips, drop wire clamps and span clamps. Also, the house brackets, cable clips, staple and steel banding are the other types of common drop utility pole line hardware materials.

§  Strut System Hardware

It is the category that functions in the form of a suspension in the overhead line structure. The strut system consists of various components that also play a fundamental role in accomplishing the effectiveness of a particular application. Some of the strut system hardware can be quite small, but they still play integral roles in the entire overhead line mechanism. Examples of some of these components include channel nuts with springs, channel nuts without springs, and combo nut washers.

Channel nuts

Also, stud nuts with springs, without springs, and channel nuts with plastic cups and studs are among the strut system hardware.

§  Quick Release Pins

Also, a common category of utility pole line hardware these items firmly help in aligning and fastening two applications. What happens when using these pins is that once you insert them into a particular application, it becomes difficult to remove them. Incidentally, it’s only removable upon depressing a button on top of the T handle or sunken grip.

These products are available in different sizes, lengths, and also designs. So it becomes easy for you to merely choose the appropriate one accordingly.

§  Distribution Hardware

Now, there are common types of hardware applicable in a wide range of overhead structures for transmission systems. They’re specifically designed to assist in enhancing the transmission of various elements from one point to another. These items could be as many as possible in a particular transmission system, but they all play unique roles in every application.

Transmission line

Some of the widely used types of distribution hardware include cut out arrestor brackets, strain yokes, and transformer mounting. Significantly, those are the key categories and examples of utility pole line hardware. However, you should always have in mind that there could be more depending on the type of overhead line structure.

Transformer mounting

The bottom line here, nonetheless, is that the uses of these accessories are unique. Therefore, you got to ensure you make the right selection for the right task.

Key Considerations when Buying Suitable Pole Line Hardware

As we move to this point, the primary emphasis that I’d like to put across is that this hardware is nowadays all over the market. You can simply get online and make your order from a particular online store, and within a short period, you’ll have it. Alternatively, you can get to a physical vendor and make your selection of the actual pole line accessories then leave with them. But tentatively, something that should always cross your mind is the fact that not all these pole line accessories are suitable for your needs. It thus implies that you have to figure out appropriately and identify the particular properties which you require from a certain accessory. For that reason, let me take you some of the general factors that you should look into when buying a fitting pole line hardware;

I. Type of Material

Without mincing words, this is arguably the most significant factor to consider when looking for a suitable pole cable accessory. You see, all these accessories are made of a wide range of materials including steel, plastic, rubber, and glass, among others.

Cross arm made from steel

Therefore, when purchasing, it is indeed ideal for determining the type of material that the item is manufactured with. Also, you need to figure out whether or not that type of material befits the purpose of the hardware in discharging its duties.

II. Design of the Accessory

When I talk of the design, I also mean the shape, size, diameter, finishing, and color of the hardware if any. What happens is that some pole line accessory manufacturers often use this factor to gain leverage in the market. So they manufacture the products with different or unique designs to stand out and attract users in various ways.

Different designs of socket clevis

Well, this could be an added advantage to some extent, but the bigger picture is whether it affects performance and efficiency. And while you’d be thinking of buying a particular accessory due to its design also consider knowing whether the design improves effectiveness. Furthermore, you must also ensure that irrespective of the design it has to fit and conform to the necessary standards.

III. Safety Rating

When selecting suitable pole line hardware, safety ought to be a top priority. Remember, this is an item you’re using to construct or fix a component that many people and properties will be using. So first it’s of utter essentiality to safeguard these lives and properties before anything else. This is to means that you must find out how many accidents have been as a result of that particular model prior to if nay. For the likes of the distribution pole line hardware, you must also establish safety measures that they provide before purchasing. And finally, you have to ensure that they meet the regulator’s safety standards before purchasing.

In fact, a suitable brand shall always make sure that it goes above and beyond to put all integral safety measures in place. If you’re a novice in this sector, you might as well consider getting assistance from an expert who understands the aspects.

IV. Type of Application

So far, I’ve spoken about the type of application quite broadly, but I am still emphasizing the same regarding selection. You see, the design for this hardware is specifically for particular applications. Of course, there are a few exceptions where some apply to different uses. But even though you have to verify their suitability in each and whether they have any effect on performance.

Pole line hardware for different applications

Essentially, determining the type of application is an ideal way of ensuring that you’re selecting the right pole line hardware for the task. It is incidentally the typical way of attaining the best accessory that guarantees performance, efficiency, and convenience.

V. Resistance to Various Conditions

Ideally, all the pole line hardware is fixed in a manner that exposes them to a wide range of environmental and physical conditions. What I mean here is that even the ones in some form of enclosures are still put outside where weather conditions can be unfavorable. And it’s for that reason that you need to ensure you go for a pole line accessory that has ultimate resistance to such conditions.

The electrical transmission line in the sea

Corrosion and rust are some of the major weather conditions that often affect the suitability of this type of product. Also, they have to be durable in the sense that irrespective of the extent of unfavorable conditions, they could still endure and perform excellently. And for that reason, it’s always advisable to go for reputable brands that have stood the test in the market.

VI. Cost of Buying

Well, this is the other relatively sensitive element that you need to consider when purchasing these items. On many occasions, you’ll find that the pricing of a particular accessory varies from one dealer to another vendor. Significantly, the cost of buying different models also depends and it’s the reason you need to determine your budget first. And if you want a better deal, especially when buying these items in bulk, it’s recommendable to do a broader search before settling on one. This way, you’ll have to choose the one that suits your budget and the quality standards that you require. And talking of quality, let us now find out the type of materials you’d necessarily go for in choosing pole line hardware.

Pole Line Hardware Materials

What usually happens is that manufacturers understand the particular requirement for specific pole line hardware. And that is the reason you’ll find materials for such components vary depending on a number of factors. Remember earlier on I’d state that the type of material for the hardware is unquestionably a significant factor to consider. In line with this, you have to understand that manufacturers often use several types of material to create these products. Some of the conventional materials for manufacturing pole cable accessories include the following;

§  Carbon Steel

This is apparently the highest rated material for producing various types of pole line accessories. It is essentially an alloy of carbon and iron or better still you refer to it as steel with carbon content. This material is vital for manufacturing various forms of pole line hardware as it contains some suitable properties. One is that carbon steel is hardy and resistant to numerous environmental aspects, including harsh weather, rust, and corrosion. For a fact, carbon steel becomes even harder and stronger when subjected to heating, which arguably makes it the best option for these applications. The good thing carbon steel is an ideal material for such hardware because it’s available in a variety of qualities. Now this means that you can find it in lower, medium, and higher qualities. So what this translates to is that the steel becomes more brittle and stronger if it contains more carbon. Again, it’s an indication that you can regulate the level of carbon to use in manufacturing a certain part of the pole line accessory.

Steel electrical cross arm

This material is utterly suitable for most robust utility pole line hardware, especially those that hold heavy loads. It follows that carbon steel hardly breaks or becomes weak, so that’s a considerable property making it suitable for utility pole line hardware.

Furthermore, carbon steel is also resistant to heat, corrosion, and rust. And since most of the overhead line hardware is always exposed to different conditions, it becomes a suitable material for these items. Some of the notable pole line accessories made of carbon steel include fasteners, dead-end components, towers, and aerial drop hardware. Of course, not all of these are manufactured using carbon steel material. So let’s find out some of these types of materials too.

§  Polycarbonate

This is also the common material common for manufacturing different types of pole line hardware. You see, one underlying factor of any material befitting pole cable accessory is that it has to be resistant to various adverse conditions. And polycarbonate is one of these materials that will never let you down when it comes to high resistance and durability.

Insulators are the common hardware that widely uses polycarbonate material. Also, some components such as pole line electrical enclosures like the meter box and similar parts are also conventional with polycarbonate. In other instances still in pole line hardware, polycarbonate is used in making dead-end equipment and many more.

§  Aluminum

Aluminum

Aluminium is the other suitable material for manufacturing this type of hardware. This metal is light, durable and functional, making it one of the key materials for manufacturing various types of pole cable accessories. If you’re keen enough, you’ll notice that other than carbon steel, most of the hardware for overhead line structures is made of aluminium. Some of them include lashing clamps, cable lashes, suspension clamps, tap brackets, cable straps, cable dampers, and clevis, among others. It is also reliable, strong, and stable making it an ideal choice for manufacturing these types of hardware.

Evidently, you’ll find some parts made from other relatively unknown materials. However, you should always ensure that such materials meet the necessary standards, especially from the perspective of safety. Right now, though, we want to move a step further in this guide to find out some of the various types of the pole line hardware.

And talking of varied applications, we’ve seen how different pole line hardware plays various roles in a number of applications. So, it would be prudent to now look into these applications in detail to find out more about how they relate to these components. Let’s find out more regarding the same in the next section.

Applications of Pole Line Hardware

Like it is apparent that the types of pole line hardware vary, that’s how the installation process for each type also varies. For that reason, it would be ideal to know the right type of this pole line accessory to use in a particular application. But in general, you can find them applicable to most of the aerial overhead line constructions including the following;

§  Transmission Line

It refers to a specific system of structures, insulators, wires, and various hardcore accessories which carry and relays electricity from one point to another.

Power transmission line

Typically, these types of lines operate at a comparatively high voltage and have the ability to transmit electricity over long distances. Clearly, a transmission line uses quite a number of pole line hardware. It follows that connection of several components of this particular unit call for the use of different hardware. The hardware applicable in a system line is ordinarily made from a wide range of materials, commonly conductors. But you might as well find other non-conducting pole line accessories made of polycarbonate or mere plastic among others. For instance, the meter enclosure and yoke plates, among others. But the most important thing, however, is to make sure that any particular hardware you purchase, has to fit appropriately.

§  Telephone Pole Line

This is also the other type of application where the use of pole line hardware is seemingly common. It is basically an overhead line that hosts a wide range of telephone communication parts, equipment, and components. So what happens is that several types of accessories are used in anchoring, holding, and fastening these parts and components.

Telephone pole line

The good thing is that most of this hardware is easily obtainable as long as you know the precise type that you need. However, the types of telephone pole lines may, at times, vary depending on various factors. In this case, it implies that you’ll need to have a particular type of hardware and install it accordingly. The most important thing regarding this application is finding the specific type of hardware that enhances performance and efficiency.

§  Utility Pole Mounting Line

This refers to a type of post or column that supports overhead power lines and a wide range of public utilities. Some of these public utilities may include fiber optic cable, electrical cables, and other components like transformers and street lights among others.

Utility pole line

This type of pole is inherently multipurpose and can be used in supporting several overhead lines simultaneously. But the primary purpose of this type of pole is to carry different kinds of electric lines and sub-transmission lines.

For that reason, it’s quite evident that this type of mounting line uses a number of pole cable hardware. Because for one, you have to ensure that all the overhead cables serving different purposes are insulated. In fact, this is the ideal way of preventing them from messing up and causing danger to different users and properties.

The good thing, however, is that hardware for utility mounting lines can be made from different types of materials. So in many instances, you’ll find that various materials including fiber, glass, metals, and plastics, among others, make up some of this hardware. Therefore, it is fundamentally the nature of the purpose that this type of pole serves, which makes it somewhat necessary to incorporate various accessories.

The essentiality of this hardware is to provide safety and efficiency for the different services that the utility poles offer. Well, these are the basic and common applications of various pole line hardware. At times you may also find that some of these accessories are used even in underground line structures.

Installing a Pole Line Hardware

Now, this is one of the most sensitive aspects concerning pole line hardware. By the way, identifying and purchasing them also requires knowledge, but installation is what ultimately matters. You see, the many times that the installation of this hardware takes place, you’ll always find a group of engineers on site.

Well, it’s an indication of how much expertise is necessary for carrying out the task. So in simple terms, what I’m trying to say here is that first before you think of installing these pole line accessories, ensure that you have the relevant knowledge. You must also make sure that you have all the right tools and equipment for doing the job as a way of improving efficiency.

Now let me give you a few ideas for installing these components on overhead line infrastructures. First, it depends on whether this set up is for the new system, repair, or replacement. These are basically what determines the installation process. But for the sake of all of these perspectives, let’s start with a general installation of a new overhead line structure.

i. Site Clearing and Preparation

The moment the project obtains all the relevant permits, the construction crew begins to clear and prepare the site accordingly. The extent of clearance will depend on the nature of the site. If it requires much detail, then the task will also be thorough. What you should give importance, in this case, is ensuring that the vegetation around won’t grow later to interfere with the line.

During preparation, a fundamental element to always consider is the accessibility of the site. Make sure that machinery and other heavy equipment can get access to the site if necessary. Remember you’ll be using vehicles to carry most of these pole line hardware to the site since they’re seemingly heavy.

ii. Installing the Structure Foundation

The next step in this process is drilling the foundation for the new infrastructure. It merely involves drilling holes, which then you fill using concrete to form formidable foundations. Once the drilling of the holes is complete, the steel bars are placed in every hole then the holes are filled with concrete.

iii. Fixing New Structure

Once you’re done with curing the foundation, you can then begin to install the transmission structure. Remember it is this structure that will enable you to fix all the relevant pole line hardware upon erecting it. So you have to ensure that you get every bit of its installation right to prevent unnecessary inconveniences later on.

If the poles or steels are relatively heavy, you can opt to use cranes to lift them as the fastening of the same continues. If you have all the materials readily available, fixing and erecting the new overhead structure may take at most three days.

iv. Stringing of Pole Line Hardware

Now, this is the point where you’ll have to start fixing all the compatible pole cable accessories accordingly. You have to be keen on whatever connection you make here because it is the ultimate stage that defines the entire process and functionality.

Of course, the engineers on-site have testing devices for determining whether all the stringing of cables is rightfully done. And of course, there is also a manual for installing particular hardware in this structure. Always ensure that you have all the relevant tools and equipment that would allow you to install these accessories well. And once every component is in place, you can then choose to carry out a test to determine whether or not everything is alright.

v. Set the Line ON

At this stage, you have finished the installation. What you do now is primarily setting it on so that it can serve the users, respectively. And it is that simple. However, if you want to replace or repair the pole cable accessory, you’d start at step 4. It would be mainly about establishing the right pole line hardware and using the right tools to replace and repair them. So it’s basically what you require to do in installing these items. The most important thing that you need to do is to ensure your safety and that of your surroundings. Therefore, always take safety precautions at all times whenever you’re engaging in any activity regarding the installation of pole line hardware.

The package quantity isn’t confirmed, it’s usually according to the size and weight of each pole line hardware fitting. The pole line hardware hot forged process is a little more complex.

The brief description is as below:

1)The first step is to heat the steel rod to a high temperature until it changes from black to red. At the same time, the shape of the steel rod is altered. The rod is crushed to a big red block.

2)The second step is to press the red block to a specific shape. If the line hardware can’t be a particular shape by a single pressing force, the pole hardware suppliers will press it twice continuously.

Rax Industry pole line hardware is mainly used on overhead power lines or power transmission lines. For the wooden pole, some pole hardware fittings are mounted by a screw machine. The flat and angle steel are used to support other electrical pole accessories. All the pole hardware fittings are connected by bolts nut and a washer.

Pole line hardware used on overhead power lines and communication lines is usually confused by people. How to identify the difference between the power line and the communication line?

Usually, For the power line and communication line, the pole line hardware is designed in different ways.
