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.
