Product use and characteristics
This product is a double-column horizontal fracture central breaking structure, the formation of horizontal insulation fracture after opening, suitable for substation when there is voltage and no load to disconnect and close the circuit. Ground switches can be attached to one or both sides. The isolation switch is equipped with CJ2 or SRCJ type electric mechanism for three-phase mechanical linkage, and the ground switch is equipped with CS14G type human-operated mechanism for three-phase mechanical linkage.
