SLG-12 indoor high voltage AC vacuum switchgear is a complete set of power distribution device with 3.6-12kv, three-phase AC 50Hz, single bus and single bus section system. It mainly uses the power distribution of thousands of industrial and mining enterprises, the power receiving, power transmission, automatic reactive power compensation device of the secondary substation of the power system and the starting of large high-voltage motor for control, protection and monitoring. It can also be used for high-voltage side protection of outdoor box type substation, outdoor high-voltage cable distribution box for urban cable distribution, etc.

The switch and main electrical components are integrated modules, the outward movable connection parts adopt labyrinth insulation structure, and the interphase conductive parts are solid insulation packaging.
