HD13 series knife switch with central frontal leverage mechanism is mainly used in switch cabinet with front operation and rear maintenance and leverage mechanism is installed in right front

Application Scope

lt is applicable to electric power line with AC 50Hz,rated voltage up to 1000V and current at or below 6000A as load-free operation to isolate power supply
Structural features
1.There are two knives located on both lateral side of static contact in the knife switch, which are locked with leaf spring and bolts. In case of short circuit in the power network, the repulsion of contact is compensated due to electromagnetic locking force between the two parallel knives and generated by the spring, thus realizing higher electric stability

2. Conductive part of knife switch, fixed on the stand with insulation base board out of pressed glass fiber plastic, has higher insulation capacity and mechanical strength. The higher mechanical strength of the rod out of pressed glass fiber plastic ensures the mechanical lifecycle of the knife switch
