Product Description

                                                                                          XLPE Insulated Flame Retardant Mining Power Cable

 

XLPE insulated power cables for coal mines (MYJV series) are high-performance power transmission cables designed for the coal mining industry. Using cross-linked polyethylene (XLPE) insulation, it has excellent heat resistance, chemical corrosion resistance, aging resistance and mechanical strength, and is suitable for long-term reliable operation of power systems in mines, power plants and other industrial applications. This series of cables meets strict national and industry standards, such as MT818.13 and MT386, and can provide safe and stable power transmission in high temperature and harsh environments.

 

Product standard:

IEC 60502、GB/T 12706、GB/T 9330、GB/T 19666、MT818.13, Other customer's requirements

 

Application :

1.It is used in coal mines to transport electrical energy, supply lighting equipment, transportation equipment, ventilation systems and drainage pumps and other equipment.

2.t is used in metal mines to transmit electricity, supply control systems, drive mechanical equipment and robots, etc.

3.Used in tunneling projects to supply power and control systems.

4.Mining cables are used to connect and power various mechanical equipment in mines, such as mining machines, crushers, transportation equipment, lifting equipment, etc.

 

Use characteristics:

Rated voltage, Uo/U(Um): 3.6/6(7.2)kV, 6/6(7.2kV), 6/10(12)kV, 8.7/10kV(12kV)
