The zinc oxide arrester is the most advanced over-voltage protector in the world, Compared with the conventional silicon carbide arrester, this presciption of the product improves gr-eatly the volt-Ampere characterisics of the resistor disc and increased through-current capability at over-voltage so as to dring a rad-ical changes for the characteristics of the arresters. Under the circumstance of normal operating voltage, the current through the arrester is just on microampere degree, When suff-ered from over-voltage, while the arrester will be under the circulating state and release over-voltage energy so as to protecting the power transmission equipments against the demage caused by th over-voltage.
Pollution resistance, stable performance , best of creepage distance , anti-fouling .
The switch room consists of various functional circuits(including grounding switches and load switches) sealed in the metal casing and busbar between them. The shell is made of 3-inch cold rolled steel plate(or unembroidered steel plate) welded. Each functional loop includes a load switch and a grounding switch. The load switch is composed of a vertical moving contact system and a static contact at the lower end. When the switch is closed, the contact moves downward and the load switch is connected. The ground switch is composed of a moving contact knife and a static contact knife. The upper and rear of the switch room are provided with 4 rectangular assemblers, and the front of the loop cabinet is provided with observation Windows. An explosion-proof device is installed at the rear of the ring cabinet.
