High Voltage Polymer Silicone Rubber Electrical Lightning Arrester

High Voltage Polymer Silicone Rubber Electrical Lightning Arrester
General Introduction
The zinc oxide arrester is the most advanced over-voltage protector in the world, Due to make the risistor disc of core componet mainly adopt zine oxide arrester. 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, the arrester's excellent nonlinear characteristics will make the current through the arrester incrase to several thousand amperse, 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.
Working ConditionThe ambient air temperatures is no higher than +40ºC,nolower than -40ºC;The altitude above sea level dose not exceed 1000-2000m(the plateau ares should be indicated when order);AC systen frequency is 50Hz or 60Hz;Power frequency voltage brought to bear on arrester for a long time does not exceed arrester's continuous operation voltage;Maximum wind speed does not exceed 35m/s;The earthquake intensity does not exceed 7 degrees;The filthy area should be given clear indication.
