Electric model lightning arrester

detailed：

HY2.5 W-8/18.7 series composite insulation exchange non-clearane metal oxide electric machine is mainly used for limit lightning arrester, vacuum switch or less oil switch cut through produced when rotating motor over-voltage protection rotation, motor from operating over-voltage damage.
