Electrical Porcelain Surge Arrester 66KV Overvoltage Protection Device
Electrical Porcelain Surge Protector Device Lightning Diverter
Description:
Porcelain Surge Arrester for 35~220kv alternating system
Main features: It adopts double sealing structure, the core encapsulates by molded silicone rubber which completely solves the sealing problem of porcelain housed products.
It has a two-way pressure release structure.
Its core component ZnO varistor has good pressure ratio, consistency, large flow capacity and high reliability.
E creepage distance of porcelain housed products is wide which is suitable for IV level heavy pollution areas.
Applications:
1. Distribution networks
2. Transmission line
3. Substation
4. Railway power station
5. Alternator and electromotor
