Porcelain Protective Lighting Arrester with Extended Creepage
Description:
Porcelain Surge Arrester is a device to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events.
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.
Applications:
1. Distribution networks
2. Transmission line
3. Substation
4. Railway power station
5. Alternator and electromotor
