Lightning Arrester

Lightning Arrester Overview: Distribution TypeLightning Arrester is mainly used to protect distribution transformer, cable connector and electric equipment from being damaged by lightning impulse voltage and operated over-voltage. The varistor used in the arrester is subjected to a series of physical and electrical tests to ensure the protective ability, and the high-level housing verifies the insulating properties. The arresterhas been designed and type tested according to IEC60099-4:2004 standard.
