MHYV series 7.1-44mm Flame retardant communication cable for mining purpose
Product Description
Flame retardant communication cable for coal mine is a special communication cable for coal mine with mechanical strength, moisture resistance, anti-static and flame retardant properties suitable for the mine environment.
Identification and length marking of mine communication cable; There are identification marks on the outer surface of the cable with an interval of no more than 1m. The contents of the marks include: conductor diameter, number of pairs, cable model, manufacturer name code and year of manufacture. The length mark is marked on the outer surface with an interval of no more than 1m, but it is staggered with the above marks. The mining communication cable adopts full chromatographic insulation and aluminum plastic composite sheath (that is, the longitudinal shielding aluminum tape of the cable is bonded with the sheath to form a sealed sheath), which is characterized by superior electrical performance and convenient construction.

Product technical parameters
Product features
1. Wire: annealed bare copper wire, the diameter of copper wire is 0.30, 0.42, 0.52, 0.60, 0.70, 0.80, 0.90 (mm).
2. Insulation material: high-density polyethylene or polypropylene, and the color of the insulated wire shall be marked according to the full color spectrum standard.
3. Insulated wire pair: Twist two insulated wires of different colors into pairs according to different pitches, and use the specified chromatographic combination to identify the wire pair.
4. Communication cable core structure: with 1 pair as the basic unit, more than 25 pairs of cables are combined by unit, and each unit is tied with a unit cable tie with a specified color spectrum to identify different units. Cables with 100 pairs and above have 1% reserve pairs, but no more than 6 pairs. The gaps in the cable core are filled with petroleum jelly.
5. Cable core tape: wrapped with polyester film tape.
6. Shielding: Copper wire shielding or embossed (or not embossed) metal tape, the metal tape is longitudinally wrapped outside the core tape of the communication cable.
7. Sheath: blue high-density polyethylene. Double-jacketed communication cables are also available.
