This product is a double column horizontal fracture central opening structure, which forms a horizontal insulation fracture after opening. It is suitable for opening and closing circuits with voltage and without load in substations. Grounding switches can be installed on one or both sides. The isolation switch is equipped with a CJ2 or SRCJ electric motor mechanism for three-phase mechanical linkage, and the grounding switch is equipped with a CS14G manual operating mechanism for three-phase mechanical linkage.
