Product Description

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.

Its features: the arrester adopts ZnO varistors with excellent volt-amps curves, compared with old arresters, its advantages cover 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 assembly in the switchgear.

These products comply with the standard of GB11032-2000 and JB/T8952-1999
