| Product Description:
Zinc oxide arrester. It is the most advanced overvoltage protector in the world. Because its core element resistor unit is made of zinc oxide and various metal oxides, compared with traditional silicon sulfide arrester, the volt-ampere characteristics of the resistor unit are greatly improved, and the current passing capacity of the resistor sheet is improved. Thereby bringing about a fundamental change in the characteristics of the arrester. Under the normal working voltage of the arrester, the current flowing through the arrester is only microampere, which is equivalent to an insulator. When overvoltage occurs, the resistance value of the arrester drops sharply, causing the current flowing through the arrester to instantly increase to thousands of amperes. The arrester is in a conducting state to release overvoltage energy, thereby effectively limiting the damage of overvoltage to power transmission and distribution equipment.
