Low Voltage Distribution Cabinet, Metal Distribution Box, Power Distribution Board, Electrical Enclosure Cabinet

It is suitable for three-phase AC 50Hz, rated voltage 690V and below, rated current 4000A and below, in three-phase four wire system or three-phase five wire system and other power systems, used for power conversion, distribution and control. 

Mining general low-voltage switchgear can be used as a complete set of low-voltage power distribution equipment in the 690V and 400V power supply system of substations in underground coal mines, underground yards without gas and coal dust explosion hazards, workshops with heavy dust corrosion, and wet places of metallurgy, subway and low buildings. 

High-voltage soft starter is suitable for mines containing explosive gas (methane) and coal dust. In the AC 50Hz voltage of 10kV or 6kV lines, the control methods can be local control, remote control, network control and other control methods, used for high-power motors soft start and soft stop.

Mining explosion-proof and intrinsically safe low voltage AC soft starter (hereinafter referred to as starter) is suitable for mine containing explosive dangerous gas and coal dust. in AC 50Hz, rated voltage AC1140V (660V) power supply system, four three-phase squirrel cage motors with current below 400A can be started in many forms (such as current limiting, voltage slope and power torque slope).

This product is suitable for an environment with coal mine gas, coal dust, and other explosive gases underground, to logically control the start, stop and double-speed of the three-phase AC asynchronous motor or AC double-winding motor in the circuit of AV 1140V or 660V. And it has a joint control function.

Mining explosion-proof and intrinsically safe type multi-loop high-voltage vacuum electromagnetic starter is suitable for coal mine AC 3300V, frequency 50Hz, three-phase neutral point unearthed power supply system, local or remote control of three-phase asynchronous electric drive, to realize the centralized control of shearer, scraper conveyor, crusher, transfer machine, pumping station and other equipment in comprehensive mechanized coal mining face.

This product is mainly used in explosive gas environments containing methane and coal dust mixtures in coal mines and other surrounding media. It is used for control, measurement, and protection in power supply systems with rated voltages of 10kV and 6kV, rated frequencies of 50Hz, and three-phase AC neutral points not directly grounded.

The working time of underground coal bunker, water bunker, equipment chamber and other works in the coal mine is short. If the electric fan is used to connect the power and arrange the fan, it is very troublesome, time-consuming and labor-consuming. According to this situation, the company has developed FQ series mine pneumatic press in axial flow local fan, which is suitable for short-distance air supply during coal bunker, water bunker maintenance and roadway excavation.
