Product Description

Porcelain Metal-oxide Outdoor Lightning Arrester 69KV

Introduction:

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
