Full-sealed and fully insulated gas-filled ring-network cabinet (hereinafter referred to as "gas-filled cabinet") is a new generation of high-voltage switchgear, which has all the functions of 10KV high-voltage switchgear.

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 flameproof three-phase permanent magnet synchronous electric drum is a new low-speed and high torque external rotor permanent magnet motor independently developed by Wantai, commonly known as permanent magnet electric drum. 

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. 

It is suitable for communities, shopping malls, schools, supermarkets, substations, industrial enterprises and other power users, with Ac 50Hz, rated voltage 400V, 690V, rated current 1000 ~ 3150A power distribution system, used for power conversion, distribution and control device of the power, lighting and power distribution equipment. 

The device is used in coal mines containing explosive gas (methane) and coal dust. It is suitable for the circuit of AC 50Hz, voltage 1140V or 660V, ungrounded three- phase center. To control the forward and reverse rotating of three-phase asynchronous motor.

GGD Metal Distribution Box, Power Distribution Board, Electrical Enclosure Cabinet Product overview It is suitable for communities, shopping malls, schools, supermarkets, substations, industrial enterprises and other power users, with Ac 50Hz, rated voltage 400V, 690V, rated current 1000 ~ 3150A power distribution system, used for power conversion, distribution and control device of the power, lighting and power distribution equipment. GGD type AC voltage distribution cabinet is based on the requirements of the Department of energy, the majority of users and the design department, according to the safe, economical, reasonable and reliable principle design. The products has features of high breaking capacity, good thermal stability, flexible electric scheme, convenient combination, systematic, practical, novel structure, high level of protection, can be used as a replacement of low voltage switchgear products.

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.

Application: Used in coal mines, in AC 50Hz, rated voltage of 660V or 1140V, rated current to800, 1000A three-phase neutral point undergrounded power supply system, as a main switch or branch switch, but also as a large-capacity motor infrequently for starting control.

It is suitable for variable frequency asynchronous motor or ordinary asynchronous motor of AC 50Hz, motor power 11KW~1120KW, rated voltage 660V or 1140V to soft start, soft stop and operation process control under heavy load, its start, stop, process control curve can be set to “S” type curve, linear curve, function curve and other forms of curve.

Application: this product is applied to soft starting, soft stopping, operation process control and energy-saving application of motor in harsh environment such as coal mine, other mines, petroleum and chemical industry.

It is one of the power control power distribution equipment which is widely used in low voltage distribution system at present. Due to its easy installation, flexible use, easy to maintain, economical and luxurious.
