QJZ3-2400/1140(660)-8ML  mine explosion-proof and intrinsically safe type multi-loop  vacuum electromagnetic starter , it is applicable to the mine with explosive gas and coal dust. In the circuit with AC 50Hz and rated voltage of AC 1140 (660) V, it can control and protect the starting and stopping of 8  or less three-phase squirrel cage asynchronous motors at the same time, and can change the phase sequence when stopping. It is especially suitable for centralized monitoring of mining, transportation, mining and other working faces with concentrated power load.

ZJZ2-10/1140(660)SM This device is suitable for underground coal mine containing coal dust and explosive gas (methane). It can control the power supply of 127V grade lighting signal equipment, and the power supply is introduced as 50 Hz 1140V or 660V.

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.

Mining Intrinsically safe Velocity Sensor for Belt Conveyor. Model: GSC5000(B).

Taking advantage of the low-speed and high torque of permanent magnet motor, combined with the torque amplification function of planetary reducer and the control of frequency converter, the low-speed drive all-in-one machine has the smallest volume and the best performance. It is suitable for installation space limited and movable equipment.
