Overview        

    GKG general mine high-voltage switchgear, mainly used in places where there is no danger of gas and coal dust explosion in coal mines, such as the power supply of the central control room, car yard, general ventilation duct and main ventilation duct power distribution chamber In the system, it is used for distribution protection and control of electrical equipment with AC 50Hz voltage 3.6kv, 7.2kv or 12kv. It can also be used to directly start or start downhole fans and water pump high-voltage motors through dry reactors. This switchgear is also suitable for ground substations and power supply systems that require high protection levels such as metallurgy and chemical engineering.
