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.
