Vacuum interrupter also known as vacuum switch tube, is the core component ofhigh voltage power switch. Its main function is to cut arc off through excellent insulation of vacuum in high voltage circuit and restrain current quickly to avoid accidents and danger. It is mainly used in electric power transmission and distribution control system, also used in metallurgy, mining, petroleum, chemical industry, railways, broadcasting, communications, industrial high frequency heating power distribution system. It is characterized by energy saving, material saving, fire prevention, explosion proof, small volume, long life, low maintenance cost, reliable operation and non-pollution. Vacuum interrupter can be divided into several kinds, one for circuit-breakers and the other for load switch,for contactor,for recloser.

This series of products is molded by embedding simultaneously one-time-conductive circuit parts of vacuum  interrupter and switch to into the epoxy resin material insulation.The outside surface of vacuum  interrupter is not influenced by external environment.External insulation capability can not be affected by the dust,moisture,small animal,condensation and contamination.The product has many advantages,such as high dielectric strength,strong weather resistance performance,one-time-ciecuit miniaturization,solid structure,high reliability and maintenance free.
