Non-standard equipment (mining series) is usually used in mines and mining industries and has the following functions:
 1. Improve production efficiency: Non-standard equipment can be customized according to specific mining environment and process requirements to meet specific production needs, thereby improving production efficiency.
 2. Adapt to special environments: The mining environment is usually complex and changeable. Non-standard equipment can be customized according to the special environmental requirements of the mine to adapt to special environments such as high temperature, high humidity, and high corrosion.
 3. Improve safety: Non-standard equipment can be designed and manufactured according to the safety requirements of mines to ensure the safe operation of the equipment in harsh environments and reduce the possibility of accidents.
 4. Reduce costs: Non-standard equipment can be customized according to the specific needs of the mine, avoiding unnecessary waste and waste of resources, thereby reducing production costs.
The role of non-standard equipment (mining series) is to provide customized solutions for mines and mining industries to meet specific production needs, environmental requirements and safety requirements, thereby improving production efficiency, reducing costs and ensuring Safe Production.

The JT series products are for production workshops, control rooms and test stations in factories, especially in metallurgy and heavy machinery for control, signaling and measurement.
Made of bent and welded thin steel plates, they have front or rear doors. Measuring instruments, switches, lights and controllers can be installed on the surface. Resistors, regulators and small transformers go inside. Terminal blocks are on the sides and bottom.

This system is designed for two fire pumps, with one in operation and the other on standby. Once the operating fire pump malfunctions and stops, the standby pump will automatically start, ensuring a reliable supply of fire - fighting water. Additionally, it provides protection for the motors against phase loss, overload, short - circuit, etc

The one-drive-multiple constant-pressure water supply control cabinet receives signals from the remote-transmitting pressure gauge installed on the pipeline. It regulates the operation of water pumps to maintain a constant pressure as set by the gauge.

During periods of low water consumption, the pumps operate at a low frequency. Conversely, when demand is high, the pump speed is adjusted to ensure the pipeline pressure stays within the predefined range. If a single pump is insufficient to uphold the set constant pressure, it is automatically shifted to bypass operation. Subsequently, the frequency converter will initiate a second pump, guaranteeing that the pipeline pressure is consistently maintained at the value set by the remote-transmitting pressure gauge.

The electronic soft starter cabinet triggers thyristors and adjusts their phase angles to make the voltage climb from 160V to 400V. This creates a soft - start process for three - phase squirrel - cage motors, enabling them to ramp up from low to high speed. Consequently, the motor current gradually increases, realizing the soft - start function.

The liquid resistance step-up starter cabinet combines mechanical and electrical means to start squirrel-cage motors. It uses an electro - hydraulic water tank to generate resistance, allowing the voltage to gradually increase from a low level. This process achieves the motor's soft-start function and reduces the starting current.

The XJ-type reactive power compensation cabinet uses non-contact switches and contactors, along with power electronic capacitor switching and random reactive power direct sampling technologies. It can resist inrush current and interference, operates reliably, and withstands switching overvoltage.

Ideal for reactive power compensation in urban/rural grids, oil fields, and internal grids of industrial and mining enterprises, it can be installed on outdoor pole-mounted transformers with voltages of 10/0.4kV or 0.6/0.4kV, having extensive applications.
