220KV High Voltage Transmission Line Composite ZnO Surge Arrester with External Series Gaps
Composite ZnO Surge Arrester:
35~220kv 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.
