metal oxide surge arrester

12~42kV metal oxide surge arrester

the metal oxide surge arrester 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.
