Polymeric Surge arrester 1. Y: metal zinc 2. H: composite housing 3.great degree of volt-ampere characteristic of resistance  We manufacture 0.22-220kv Metal Oxide Surge Arrester. It is the most advanced over-voltage protector and 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.
