0.25~765kv Rubber Porcelain Housed Metal Oxide Lightning Arrester

0.25~765kV Polymer Silicon Rubber Porcelain Housed Metal Oxide Lightning Arrester with KEMA Type Test Report

1. Lightning Arrester Up to 756kV

YONGDE Surge Arresters can be applied to a variety of systems including substation equipment,

railway power system and power distribution units ranging from 0.28kV to 500kV systems.
These surge arresters demonstrate excellent protection properties. Our surge arresters incorporate

non-linear resistor ZnO elements with superior non-linear current- voltage characteristics,

high quality and reliability. Metal oxide type surge arresters offer such special features
inherent in the gapless structure, such as a quick response to surge voltage,

high energy dissipation capability, safe operation, compactness / lightweight and freedom from pollution.
