Polymeric Surge Arrester 35 KV

surege arrester is the most advanced over-voltage protector,Zinc oxide, gapless,

The 35 KV metal oxide surge arrester is widely used as protective devices against switching and lightning over voltages in power station. 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.
