Overview
MYQ mining rubber sheathed cable-2x2.5 Ping An Xi Le 2025 $r $n During use, the local bending radius of the coal mining machine cable is much smaller than the standard bending radius of the cable. The cable is frequently subjected to the combined effects of excessive bending, stretching, and other two or more stresses for a long time. In addition, the cross-sectional area of the control core conductor is much smaller than that of the main core conductor, resulting in the breakage of the control core.

During use, the local bending radius of the coal mining machine cable is much smaller than the standard bending radius of the cable. The cable is frequently subjected to the combined effects of excessive bending, stretching, and other two or more stresses for a long time. In addition, the cross-sectional area of the control core conductor is much smaller than that of the main core conductor, resulting in the breakage of the control core.
1. Increase the flexibility of coal mining machine cables used in coal mines;
2. IncreaseControl wire coreRelative slip property;
3. Increase the strength of cable conductors for coal mining machines used in coal mines;
4. Changing the conductor from the original bundle twisting structure to regular twisting can increase its bending performance, and then weaving steel wires outside the conductor to increase its strength;
5. The control wire core can be woven with a mixture of tinned copper wire and steel wire, which is also a good method.
MYQ mining rubber sheathed cable-2x2.5 Ping An Xi Le 2025
The price formula for mining cable series is as follows: weight of copper X copper price calculation: wire diameter ÷ 2=1.25X1.25X3.14=square number X number of wires X0.89X current copper price+10% processing fee. The cost price calculation of mining cables is square X1.83=weight of copper X current copper price+armor price (weight X0.4 yuan/jin)=cost price+10% processing fee. Cable price=manufacturing material cost+fixed cost+tax+business fee+profit. Manufacturing material cost=material cost * (1+material consumption) (material cost is the theoretically calculated value). Fixed costs vary depending on the situation of each company, generally including production wages, management wages, utilities, repair costs, depreciation costs, rent costs, and transportation costs
