YH5WZ-10KV Metal Oxide Lightning Arrester
Purpos
The Zinc Oxide lightning arrester is the most advanced over-voltage protector in the world. Because its core component resistors are made of Zinc Oxide and various metal oxides, compared with traditional silicon carbide arresters, it greatly improves the volt ampere characteristics of resistors, improves the capacity of resistors, and brings about the fundamental change of the characteristics of arresters.
When the lightning arrester under normal operating voltage, the current flow through the arrester only microamp level when subjected to voltage, non linear volt ampere characteristics of arrester excellent function, current flow through the arrester moment increased to several thousand amperes, lightning arrester in the conducting state, the release of piezoelectric energy, so as to effectively limit over against the voltage of power transmission equipment.
Use Condition
