Mine Cable

product description:
Mine cables are all flame-retardant cables, and they should be issued by the National Mining Product Safety Marking Center of Safety Standards to issue a mining product safety mark certificate. Mine rubber-sheathed flexible cables are suitable for mobile laying cables for mining power plants with power frequency rated voltage U0/U 8.7/10KV and below.

Product Standards:
This product is produced according to GB/T12972-2008 "Rubber sheathed flexible cables for mines", MT818-2009 "Flame retardant cables for coal mines", and can also be in accordance with the International Electrotechnical Commission recommended standards IEC, British standards, German standards and the United States according to user needs Standard production.

Use characteristics:
● Power frequency rated voltage U0/U is 380/660V, 660/1140V, 1.9/3.3kv, 3.6/6kv, 6/10KV, 8.7/10KV, 300/500V.
● Maximum allowable working temperature of cable conductor: 65℃ 90℃
● The minimum allowable working temperature of the cable is -35℃
● Cable bending radius: not more than 6 times the outer diameter of the cable.
Mine cables include MC cable, MCP cable, MZ cable, MZP cable, MYQ cable, MY cable, MCPTJ cable, MYPTJ cable, MVV cable, MKVV cable, MYJV cable, MKYJV cable, MHYV cable, UGF cable, high-voltage mining cable , 10KV rubber-sheathed cable, 6KV mining cable, mining mobile cable, mining flame-retardant cable, MCPT cable, mining rubber-sheathed cable.

How to improve the service life of the cable?

During use, the local bending radius of the shearer cable is much smaller than the bending radius of the cable specified in the standard. The cable is frequently subjected to the combined action of more than two kinds of stresses such as excessive bending and stretching for a long time, and the cross-section of the control core conductor is far It is much smaller than the conductor cross-section of the main core of the cable, causing the core of the control core to be broken.
1. Increase the flexibility of the shearer cable used in coal mines;
2. Increase the relative slippage of the control core;
3. Increase the strength of the cable conductor of the coal mining machine;
4. Change the conductor from the original stranded structure to regular twisting, which can increase its bending performance, and then braid steel wires outside the conductor to increase its strength;
5. The control wire core can be braided with tinned copper wire and steel wire, which is also a good method.
