Substation HV High Voltage Surge Arrester Protector with ZnO Varistor

High Voltage Substation Lightning Arrestor with Porcelain Housing

 

Description:

 

High Quality Porcelain Surge Arrester

 

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.

 

Polymer surge arrester production process:

 

1. Zinc oxide varistor with group
2. Core body tied, solidify
3. Degrease, coated with coupling agent
4. Core body preheating
5. Whole vulcanization molding
6. Visual inspection, secondary vulcanization
7. Factory inspection
8. Packing and warehousing
