3KV Compact Polymer Housing Lightning Surge Arrester for Power Transformers / Distributors Protection
Description:
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.
