How to improve the use of cable in mine shearer cable

In the process of use, the local bending radius of the shearer cable is far smaller than the bending radius of the standard cable, and the cable is frequently subjected to the combined effects of excessive bending and stretching and more than two stress, plus the control of the cross section of the core conductor. It is much smaller than the conductor cross section of the main cable core of the cable, causing the core of the control core to break.

1. Increase the flexibility of shearer cables used in coal mines;

2. Increase the relative slippage of the control wire core;

3. Increase the strength of shearer cable conductors for coal mines;

4, the conductor from the original bundle of twisted structure was changed to a normal twisted, so that it can increase its bending performance, and then wire braided outside the conductor, and increase its strength;

5, the control core can use tinned copper wire and wire braid weaving, is also a good method.
