Taiyuan Telephone Cable Mining Communication Cable MHYSV 14 * 1.5

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.

　　Requirements for fixed laying of high-voltage cables for mining cables:

　　1. In the vertical shaft or inclination angle of 45 ° C; In the above tunnels, PVC insulated thick steel wire armored PVC sheathed power cables and cross-linked polyethylene insulated thick steel wire armored PVC sheathed power cables should be used;

　　2. In horizontal tunnels or at an inclination of 45 degrees; In the following tunnels, PVC insulated steel strip or fine steel wire armored PVC sheathed power cables, cross-linked ethylene steel strip or fine steel wire armored PVC sheathed power cables should be used;

　　3. Aluminum core cables can be used in the air intake inclined shaft, underground parking lot and its vicinity, and between the substation and the mining area substation; Copper core cables must be used in other locations;

　　4. Fixed low-voltage cables should use Mw armored or unarmored cables or mobile rubber sheathed flexible cables of corresponding voltage levels;

　　5. Non fixed high and low voltage cables must use rubber sheathed flexible cables that comply with the Mr818 standard. Mobile and handheld electrical equipment should use rubber sheathed cables;

　　6. Cables used for lighting, communication, signaling, and control should be armored communication cables, rubber sheathed cables, or M-type, factory type plastic cables;

　　7. Aluminum cores should not be used for low-voltage cables, and aluminum cores are strictly prohibited for low-voltage cables in mining areas.

　　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.
