Self-blasting Circuit Breaker Insulation Rod

Self-blasting Circuit Breaker Insulation Rod
1.High insulation character,mechanical and operation ageing performance
2.Using the insulation rod open and close the dynamic and static contact
3.Not be allowed to occur the burn or deformation on the pole
Product Details


The function of Insulation rod(GIS- switch rod) are insulate the electrical potential and carry out the command to switch on and switch off from the substation control room by using the insulation tension rod open and close the dynamic and static contact.So that the insulation tension rod are required not only a high insulation character ,but also the mechanical and operation ageing performance. There is a very high requirement of punch or flashover along with the surface.It can not be allowed to occur the burn or deformation on the pole
