Product Description

Product Description

ZnO lightning arrester is one kind of most advanced over-voltage protector at present due to its core components of resistance applying ZnO and other metal oxide to make of comparing with traditional carborundum arrester, it improves greatly V-A charcateristics of resistance,increases the getting through ability of resistance,thereby it brings fundamental,change to features of arrester.

Under normal working voltage.The current passing arrester only A class,when bearing over voltage.The excellent non-linear V-A features of arrester would make effect,the current passing through the arrester increase high to thousands of Ampere instant the arrester is under getting through state,to release over-voltage energy therefore it effective limits the damage to power transmission equipments due to over voltage.

FAQ

Q1: What is a polymer surge arrester and how does it work?
A: A polymer surge arrester is a protective device that prevents overvoltage damage in electrical systems. It uses zinc oxide (ZnO) blocks to absorb and discharge lightning or switching surges safely to the ground, while its silicone rubber housing provides insulation and environmental protection.

 
Q2: What is the difference between a polymer surge arrester and a porcelain arrester?
A:

Polymer arresters are lighter, explosion-proof, and have better pollution resistance.
Porcelain arresters are heavier and more fragile.
Polymer types are more suitable for modern power grids, especially in polluted or high-humidity environments.
 
Q3: What voltage levels do your polymer surge arresters support?
A: We offer arresters from 3kV to 220kV, covering low-voltage, medium-voltage, and high-voltage systems. Custom ratings are also available.

 
Q4: What standard certifications do your surge arresters comply with?
A: Our products comply with IEC 60099-4 and GB 11032 standards. We also provide third-party testing certificates such as CE, Type Test Reports, and Factory Test Reports upon request.
