HXGN-12 (GZS5) series indoor AC high voltage metal enclosed switchgear is suitable for three-phase AC rated voltage of factories, residential quarters, high-rise buildings, schools, parks and other 3.6~12kV, rated frequency 50Hz power distribution system, as the power and distribution of electrical energy, which can be used for ring network power supply and power supply terminal, can also be a box type substation.
1, high safety, and a two times can be completely isolated; the main bus chamber and the load switch chamber with a grounding metal plate separated; load switch in metal valve grounding with static head fracture; between the cabinet, load switch, metal valve with reliable mechanical interlock;
2. The installation and operation are simple, and the maintenance is convenient. It is small in volume and convenient to move.
3, the operation mode is both manual and electric.
4. The main switch can be both installed and side mounted.
