Sell Surge Arresters

Detailed Product Description Surge arrester is a kind of voltage limiter, which is used to protect transmission& distribution equipment (such as transformer, switch, capacitor, voltage transformer,generator, motor and power cable etc.) from being damaged by over-voltage.As main components of metal surge arresters, our resistors feature non-linearcharacteristics (V-I), quick steep wave response, strong current-flow capacityand anti-ageing ability and so on. They greatly improve the protection abilityand reliability of surge arresters.We adopt the process of whole-injection formation and sealing from both terminalsides for composite housed metal oxide surge arresters and they feature good sealingperformance, excellent anti-explosion, anti-dirty, anti-power eroding, anti-ageing,small volume and light weight etc. They are also easy for installationand maintenance.Porcelain housed metal oxide surge arresters are of good construction, lasting sealingperformance, even potential distribution and reliable pressure relief apparatus.Normal Service Conditions of Metal Oxide Surge Arrester Without Gaps for A.C. System:1 Ambient temperature: -40+40C;2 Altitude: not more than 2000m;3 Frequency of power source is not less than 48Hz, not more than 62Hz;4 Power frequency voltage applied between terminals of surge arrester must not overpasscontinuous operating voltage of surge arrester;5 Earthquake intensity is not higher than 7 degrees;6 Max. wind velocity is lower than 35m/s.
