Product Description

Metal Oxide 54KV 5KA Class 2 Surge Polymer Housing Lightning Arrester for High Voltage Circuit

Application:

The zinc oxide arrester is mainly used to protect distribution transformer,cable

connector and electrical equipment from being damaged by lightning impulse

voltage and operating over-voltage.

Technical Specification:

1. The composite-sheath metal-oxide arrester applied in AC system.

1.1 Typical product parameters of composite-sheath metal-oxide arrester used under low-voltage.
