10kv metal oxide light arrester(surge arrester)

Zinc oxide surge arrester Sillicone rubber housing High circulation ability of the varistor ISO 9001-2008 After sale service

Zinc oxide compound sheath non-clearance surge arrester (short for arrestor) is used to protect the corresponding voltage-grade alternating current (AC) electric apparatus from the excess voltage.

Product advantages:

Its protective property is excellent and the antipollution outstanding as well as its volume is small and the weight light. Because the sheath is made from organic material such as silicon rubber and EP (epoxide) it can avoid some kind of serious explosive accident, for example the one caused by ceramic arrestor.
