How to improve the mine control cable core service life?

Information Source:Henan Huadong Cable Co., Ltd Release date:2014-02-22

Bending radius of cable bend radius local control cable mine coal mining in the use process machine is far less than the standard cable, cable frequent excessive bending, stretching from combined action such as more than two kinds of stress, conductor section plus the control wire core conductor cross section is far less than the electric cable line core, resulting in a broken core control wire core.

Can be improved from the following aspects:
1, increase the soft cable for coal mine coal mining machine;
2, increase the relative slip control line core;
3, increase the cable for coal mine shearer conductor strength.
4, the conductor from stranded structure is changed into regular stranded, this can increase the flexural performance of it, and then wire braided in conductor outside, and increase its strength
5, the control wire core can be used tinned copper wire and steel wire weaving, is also a good method
