48~62Hz, 35KV HY/Y Series ZnO Surge Arrester Protect Power System Low Voltage Products
Application
ZnO arrester is the latest over-voltage protective device, suitable for AC 48~62Hz, 35KV and below power system to limit the over voltage, protect the insulation of electric equipment from being destroyed by lightning voltage or switching over-voltage, it is one of important device to protect power system and ensure the safety of operation.
Features
The arrester adopts ZnO varistors with excellent volt-amps curves, compared with old arresters, its advantages is fast response, good steep wave, low residual voltage, large square-wave current, no continuous current, simple structure, light weight, high reliability, anti-pollution, easy maintenance and etc. Polymer type made of silicone rubber housing, no gap, good sealing performance, moisture resistant explosion proof, no risk of crack, especially suitable for switch cabinet.
standard : GB11032-2000 and JB/T8952-1999
