Polymeric Lightning Arrester Nominal Discharge Current 5kA

Application:

   Massive productions of lightning arrester (MOA), either with porcelain or polymeric housing, are suitable in the systems of power generation, power transmission, power transformation, and power distribution under AC 220kV and below. They are mainly used to keep the amplitude of lighting impulse withstand voltage and switching impulse withstand voltage to the prescribed level.
