Nonetheless, you might have no clear idea of why it is needed.

This is why I have provided detailed information on this part for you to use.

Knowing this is the first step in your process to apply this hardware accessory.

Where do we use the pole top pin?

Pole top pin is used along with pin insulators mainly on power transmission lines, 11kv/33kv distribution lines, and overhead power lines.

What are the specific reasons to use a pole top pin?

• Pole top pin is used to permit smooth or effortless removal for insulator unit replacement or fittings devoid of removing insulator strings from cross arms.
• You need a pole top pin to ensure strings aren’t damaged when used.

Connecting insulator pins might seem to be unnecessary.

However, when you ask the experts you will know how valuable they are in pole line and overhead line construction projects.

If you have found yourself in a situation where you need to purchase and install them always read the right guides.

Pole Top Pin Manufacturing Process

I believe you really need or wish to obtain information on the process of making pole top pins.

If you do that is great.

There is nothing wrong with wanting to know this.

Technical specifications of pole top pin

To begin with, there is the need for you to know that pole top pin hardware accessory is made from hot new rolled steel.

The process of manufacturing includes:

1. The process begins by heating the steel to become very red.
2. After that, it is punched to obtain the shape it has.
3. Its finish is hot dip galvanized and this is ideally smooth and has no burrs or projections that are sharp.

Knowing this helps you to obtain the right information as it is needed.

Not all suppliers use the right method to manufacture their pole top pins.

Most people have no idea of checking or knowing the top hole size.

However, they always help with installations and that is a good thing.

• Spacing Bolt

Pole top pins, and hardware accessories are used in fastening and deciding the space between the bolts.

There are times when bolts must be spaced in specific measurements for specific purposes.

Try to have these understood for your own benefit.

• Insulator Thread Material

Insulator thread materials are used to remove insulator strings from cross arms.

The Pole top pin has a length of 18’’ and 20’’, with 1’’or 1-3/8’’ lead thread.

Step-by-step Process How to Install Pole Top Pin

Installing a pole top pin is not something that is complicated.

However, you need to be sure about the actual process.

Sections of pole top pin
