CKFL-12S SF6 Load Break Switch
CKFL-12S type load break switch is designed with three positions, rotating type movable contact; the shell is made of high strength pressure casted epoxy resin using SF6 as arc extinguishing medium. Every switch is sealed by filling gas under 0.045MPa pressure, and they all passed helium leakage test without gas leakage. The switch can be installed vertically or horizontally, the typical method is to be horizontally installed with steel clapboard between the cable cabinet and the bus bar cabinet. If arcing happened inside switch, a structure weak spot on the back of the shell would be burst through and release the high pressure gas.
