35 кВ Оксид цинка Молния перенапряжения

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.The specification of 35KV metal oxide surge arrester Type System rated voltage KV MOA rated voltage KV Continuous operating voltage KV Reference voltage at 1 Ma Residual voltage at nominal discharge current Steep current impulse residual voltage 2ms rectangular current impulse withstand YH5WZ-51/115355140.866115133400/600YH5WZ-51/128 355140.873128148400/600YH5WZ-51/130 355140.873130150400/600YH5WZ-51/134 355140.873134154400/600YH5WZ53/134 35534178134154400/600YH5WZ-42/122 354223.466122140400/600YH10W-45/135 354523.470135155400/600 1.
