Zinc oxide arrester

Applicable scope:

Zinc oxide arrester is mainly used for power distribution which is 110kv and below voltage, to limit the over-voltage may appearing in the system, in order to ensure the safe operation of power transmission equipment

According to the user's needs, there are five choices of distribution type, power type, parallel group protective container store, rotate motor protection, electric railway. In the cathodic protection industry, the main role of lightning arrester is lightning protection of grounding battery.

Features:

Zinc oxide arrester has a good volt-ampere characteristics and excellent protection performance and impact response characteristics and high tolerance for multiple lightning and operating voltage capability, good stain resistance, etc., and simple structure, convenient installation and maintenance, long life cycle, can provide the best protection for power transmission equipment.
