This load switch is a double-break rotary load switch with SF6 gas as insulation and arc extinguishing medium, suitable for 12kv power distribution system. Each switch is permanently sealed after being filled with 0.045MP-0.06MP pressure SF6 gas. The switch can be installed vertically or horizontally. The typical installation method in the ring network cabinet is to install it horizontally with a steel partition between the cable room and the busbar room. This installation method isolates the busbar from the cable line connector to meet the most stringent safety requirements for operation and maintenance.

If the line fault generates excessive current and causes arcing inside the switch, there is a structural weak point at the rear of the shell, which will be opened, and then the arc discharge valve on the cabinet will be opened and the overpressure airflow will be directed to the outside of the cabinet.
