开采橡胶电缆护套的防火燃油胶-证明纯铜电缆

Types and Models

Coal mining cables include a wide range of types and models, such as mc cable, mcp cable, mz cable, mzp cable, myq cable, my cable, mcptj cable, myptj cable, and so on. In addition, there are also cables designed for specific application scenarios, such as SHD-GC mining cable, which is designed for mobile equipment in the mining industry, with flame retardant, oil resistance, moisture resistance, low abrasion and other characteristics.

Categorize

According to the construction can be divided into rubber cables, armored cables and plastic cables; according to the use can be divided into signal communication cables, control cables and power cables; according to the voltage level can be divided into low-voltage cables, high-voltage cables; according to the cable core material can be divided into copper-core cables and aluminum-core cables.

Performance characteristics

(1)Flame retardant: coal mine cables are flame retardant cables, in line with the relevant flame retardant standards, to ensure the safety of the mine and other flammable and explosive environments.

(2)Temperature resistance: the maximum allowable working temperature of the cable conductor is usually between 65℃~90℃, and the lowest allowable working temperature is -35℃, which is suitable for the complex and changeable working environment in the mine.

(3)Flexibility and abrasion resistance: cable wire is soft, structurally stable, not easy to kink, and has a certain degree of abrasion resistance, suitable for frequent movement and bending in the mine.

(4)Shielding and protection: Many coal mine cables use metal braided shielding to improve the uniformity of the electric field, while the outer sheath is thicker to enhance the protection of the cable.

Product Applications

1.Power Transmission

Coal mine cables are the main means by which electricity is transmitted from the power station to all areas of the mine. Whether it is high voltage power supply to large production equipment or low voltage power supply to auxiliary equipment such as lighting and ventilation, coal mine cables play a vital role.

2.Signal Transmission

Coal mine cables not only transmit electricity, but also undertake the task of signal transmission. For example, in the mine hoist system, cables are used to connect the hoisting motor and the control system to ensure the smooth running of the hoisting operation. In addition, they are also used to connect various electrical control equipment with the control center to transmit control instructions and feedback equipment status signals.

3.Lighting System

In an underground coal mine environment, good lighting is key to ensuring worker safety and productivity. Coal mine cables provide power to underground lighting fixtures, ensuring adequate light in the work area, reducing the risk of accidents and improving work efficiency.

4.Safety monitoring

Coal mine cables also play an important role in safety monitoring systems. It connects gas sensors, personnel positioning systems, video surveillance equipment, etc., transmitting data in real time to ensure mine safety.

5.Power supply for mobile equipment

Coal mine cables also supply power to underground electric motors, ventilators, drainage pumps and other fixed or mobile large-scale production equipment to ensure the normal operation of the equipment. Especially in open-cast coal mines, such as material cranes, shovels, drills, excavators and other equipment that require frequent mobile operation, coal mine cable is indispensable.
