Elbow Surge Arrester
Elbow surge arrester offers shielded deadfront arrester protection with metal oxide varistor elbow, along with parking stand arresters. It allows the installation on standard separable connector bushings and its primarily used to protect underground distribution systems.
The installation is done at the open point of underground system to avoid doubling of the voltage wave. It can also be installed at the middle point to harmlessly discharge voltage reflections from the open point arrester.
Constructed from peroxide cured EPDM rubber, the housing of elbow surge arrester is completely shielded with a molded conductive EPDM jacket to facilitate the concept of dead front. The EPDM rubber is also fully submersible for various applications.
The designs of 27kV, 18kV and 10kV rated arresters are used on nominal 35kV, 25kV and 15kV UD systems, respectively. These three ratings entail standard ANS/IEEE 386 separable connector interface designs whose compatibility aligns with each voltage level of major interface suppliers.
Key Features
- Compact size that facilitates easy installation in existing cabinetry and saves time
- EPDM rubber construction for complete submersible and shielded applications
- IEEE 386 interface to facilitate convenient energized connection with other 200 A deadbreak components
- Varied discharge voltage
- Ground lead for controlling end plug and avoiding uncontrolled trajectory
- Flexible 4 AWG ground lead
