Embedded pole series

Insulating materials are used to seal the vacuum interrupter and the main circuit conductive elements. The insulating supports are reliably sealed into a whole part, which has the advantages of simple assembly, stable quality, high reliability and strong resistance to environmental pollution. Application: it is equipped with corresponding indoor and outdoor vacuum circuit breaker or vacuum distribution device, especially suitable for those with frequency of 50Hz/60Hz, rated voltage of 12kV, 17.5kV, 24kV, 27.5kV, and 40.5kV power, machinery, chemical industry, metallurgy and mining departments, which operate frequently under full operating conditions.
