Coal mining machine cable, photoelectric composite cable

Coal mining machine cable is a power cable specifically designed for underground coal mining machines, used to provide power connections for the machines. It is a type of cable used in coal mines. Application of Coal Mining Machine Cable---Mainly used for rated voltage of1.9/3.3kVThe0.66/1.14kVPower connections for coal mining machines and similar mobile devices below. According to the coal industry standards, the cable models for coal mining machines are usually “M” The beginning indicates mining“C” Used for coal mining machines“P” Representing metal shielding“T” Used for dragging“J” Indicates the monitoring core. Common models includeMCTheMCPWait. In terms of specifications, the nominal cross-section of the power core conductor is16mm²、25mm²、35mm² There are various cross-sectional specifications for the ground wire core and control wire core, and they are also wound and twisted in a spring like manner to increase strength and flexibility, solving the problem of bent and broken cores. The insulation layer is made of rubber composite material mainly composed of ethylene propylene rubber, which has the characteristics of high insulation resistance, strong heat resistance, and bending resistance.

Sheath: usually made of chloroprene synthetic rubber composite material, with strong tear resistance, good wear resistance, resistance to grease and chemical corrosion. Has good insulation performance,20At ℃, the insulation resistance is high, and the power and control wire cores can withstand the specified power frequency voltage test without being broken down.

The cable of the coal mining machine complies withMT386Requirements for various flame retardant tests in.

Cable laying of coal mining machine---When laying, it should be consistent with the direction of the tunnel, and the bending radius at the turning point should not be less than 10 Double the outer diameter of the cable; The distance between suspension points in horizontal or inclined tunnels shall not exceed2mWhen put into operation, it needs to be inspected by a dedicated electrician. Mobile equipment cables should be inspected by a dedicated person every shift, and the connection points between cables and explosion-proof equipment should be checked regularly to ensure a secure connection
