Solid sealed pole technology is the embodiment of the tremendous progress of the vacuum circuit breaker technology.

Vacuum circuit breaker extremely column insulation experienced air insulation, composite insulation, solid seal insulation,Solid sealed pole insulated by the APG process, the use of epoxy resin will  encapsulate the interrupter and the upper and lower outlet seat,this would not only shrink the size of the interupters but also completely free from the external environment.
