Y Series
Porcelain Insulation Arrester

Y Series Porcelain Insulation Arrester


Y Series uses zinc oxide resistors as its core components, so compared with traditional silicon carbide arresters, it has good volt-ampere characteristics and voltage current capacity, which can effectively protect the electrical equipment of the AC power system from atmospheric overvoltage and excessive operation. voltage damage.
