Product description:

Zinc oxide Arrester

Zn lightning arrester is a kind of world advanced over-voltage protector at present, due to its core components of resistance applying Zn and other metal oxide. Comparing with traditional carborundum arrester, it improves greatly V-A features of resistance, increases the getting trough ability of resistance, thereby it brings fundamental change to features of arrester.

Under normal working voltage, the current passing arrester only is UA 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.

Usage feature:

Zn lightning arrester is the protective electrical equipment to protect AC electrical system and prevent the damage of high voltage and over voltage operation.
