Surge Arrester
Insutek AHY series of Rear Connector with arrester, is to provide lightning protection, and over-voltage protection, which can effectively ensure the safe operation of power grids.
Feature:
- Rear connector with arrester protects electric apparatus . from lightning and over-voltage.
- Arrester is adopted special explosion-protective separable device.
- The arrester can keep in good operation under the condition of broken because of longtime aging or thunder lightning strike.
- Protect the arrester from explosion or permanent earthing fault.
- Guarantee the grid running safely.
