China 8.7/15kV European Arrester factory and manufacturers

8.7/15kV European Arrester

8.7/15kV European arrester can be directly connected with casing seat, wall through casing, etc. The

rear plug arrester is connected to the front plug or another rear plug to provide overvoltage protection for

electrical equipment
