Polymer 42KV Transmission Line Surge Arrester for Power Transformers

Polymer Housing 42KV Metal Oxide Surge Arrestors Diverters

Description:

Polymer Housed Metal-Oxide Surge Arrester is mainly applicable for protection of the power equipment like transformers against system over-voltages and lightning surges. It is manufactured with excellent voltage-ampere characteristics and high level of reliability and durability. And the arrester is designed and type tested according to IEC60099-4:2004 standard.

42-75kv Main features of Surge arrester with external series gaps (for transmission line protection)
With smooth volt-second characteristic curve. Good insulation coordination and protective characteristics.
The electrical frequency withstand voltage is high in discharging gap, high reliability, low allocated voltage, minimum aging phenomenon.
Tube-like structure, injection hole to the side, overall injection molding polymer housed, no internal air gap, the core columns is encapsulated independently, with better air-proof performance than the other tubing products.
The injection hole to the side with a pressure release function.
The flow capacity of core component zinc oxide varistor reaches 100kA.
Good anti-fatique behavior with Polymer Housed products and a CTI level of six. Creepage distance meets the requirements of III level heavy pollution.
