Lightning arrester YH5(10) WT-42/120

The lighting arrestor is the most advanced over-voltage protector. It is widely used as protective devices against switching and lightning over voltages in power electrical systems such as power transformers ,distributors,generators, compensation capacitors. Its core component--resistance slice adopts the material including zinc oxide and many kinds of metal oxides, compared with traditional silicon-carbide arrester,its volt-ampere characteristic of resistance slice has been improved to great degree, as well as the current-transmit ability of resistance slice, as a result, the capability of arrester has been improved basically and thoroughly. 2, The metal-oxide surge arresters without gaps for electric railway, which is used to protect all kinds of electrical equipments, contact network, electric locomotive from the damage of atmosphere overvoltage and operating voltage. 3, Main electrical parameters of polymer-housed metal-oxide surge arresters without gaps for electric railway
