Lhasa telephone cable mining communication cable MHYVP1 * 4 * 1/1.38

Description :

　　A communication cable is a communication line composed of multiple insulated wires or conductors twisted into a cable core and an outer sheath that protects the cable core from moisture and mechanical damage. In particularly harsh environments, a protective layer can be installed outside the communication cable sheath if necessary.

　　Mining cable is the abbreviation for coal mine cable. Mining cables are all flame-retardant cables and should be issued with a mining product safety mark certificate by the National Mining Product Safety Mark Center. U-shaped (M-type) rubber sheathed cable for coal mines.

　　Characteristics of using mining cables:

　　1. The rated voltage U0/U of the power frequency is 380/660V, 660/1140V, 1.9/3.3kv, 3.6/6kv, 6/10KV, 8.7/10KV, 300/500V;

　　2. The high allowable working temperature for cable conductors is 65 ℃ and 90 ℃;

　　3. The cable allows a low working environment temperature of -35 ℃;

　　4. Cable bending radius: not greater than 6 times the outer diameter of the cable.

　　Mining cable control core:

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

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

　　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.

　　Selection of Mining Cables:

　　In the mine power supply system, high-voltage power supply lines generally use armored cables, which have a much lower failure rate compared to low-voltage power supply. The power supply in mining areas is a weak link in the power supply system, and the working environment is poor. Therefore, how to choose the type and cross-section of cables is related to the safety of power supply operation. The following introduces the selection of cables and the method of selecting cable cross-sections.
