Structural characteristics of mining rubber sheathed cables:
1： Conductive wire core. The flexibility requirements are highest for electric drill cables and mining machine cables; The following measures are taken for the wire structure:
1. Use softer small-diameter copper single wires, bundled and twisted at small intervals. The bending and twisting properties of the entire cable are also affected by the insulation and sheath structure, so it cannot be assumed that the finer the single wire, the smaller the pitch, the better.
2. Adopting co directional bundle twisting and compound twisting can improve flexibility.
3. In order to facilitate the relative sliding of wires in the insulation layer and facilitate installation and maintenance. The single wire of drill cables and small section mining machine cables should be tinned, and the large section mining machine cables should be insulated with paper tape outside the wire.

2： The insulation layer requires sufficient electrical insulation performance
1. Use rubber with a rubber content of not less than 35%
2. The insulation thickness is thicker than that of general rubber sheathed cables
3. Use rubber with good electrical properties and adopt good extrusion technology (such as extrusion vulcanization continuous production line)
3： Shielding layer
The use of non-conductive rubber as the shielding layer should ensure that its transition resistance meets the standard requirements to ensure reliable operation of the relay protection system in case of accidents.
4： Pad core
1. The pad core should fully serve as a buffer when the cable is subjected to impact or compression, while not being too large in outer diameter. Require a reasonable design to fill the gaps between insulated core wires.
2. The mechanical performance should not be lower than the requirements of insulating rubber.
3. It should not adhere to the insulated wire core.
5： Cable structure
1. Use smaller pitch multiples to improve the flexibility of the cable.
To ensure the mechanical strength of the ground wire core, the cross-section of the ground wire core is larger than that of general cables. For small cross-section products, the same cross-section as the main conduit is used.

How to prevent wires and cables from catching fire
1. Ensure construction quality, especially the production quality of cable heads, which must strictly comply with regulatory requirements.
2. Strengthen cable operation monitoring to avoid cable overload operation.
3. Conduct cable testing on schedule and promptly address any abnormalities found.
4. Cable trenches should be kept dry to prevent cables from getting damp, which can cause insulation degradation and short circuits.
5. Regularly clean the accumulated dust on the cable to prevent the dust from self igniting and causing the cable to catch fire.
6. Strengthen the regular calibration and maintenance of cable circuit switches and protections to ensure their reliable operation.
7. When laying cables, it is necessary to maintain sufficient distance from the heat pipe and control the cable to be no less than 0.5 meters; The power cable shall not be less than 1 meter. Control cables and power cables should be routed, layered, and arranged separately, without overlapping between layers. For parts that do not comply with regulations, flame-retardant and thermal insulation measures should be taken for cables.
8. Install fire alarm devices to promptly detect fires and prevent cable fires.
9. Take fire and flame retardant measures
