● Product Use:
This product is mainly used for wet and slanted lines of communication; -30 ° C to 60 ° C environmental conditions, coal use communication cables MHYAV, mechanical and electrical properties remain unchanged.
● Product Description:
MHYAV coal insulated aluminum - polyethylene bonding layer PVC sheathed communication cables,
● MHYAV mine communication cable, said method: (20 × 2,30 × 2, 50 × 2) × (0.5,0.6,0.7,0.8,0.9,1.0 mm);
● product structure:
1) Conductor: annealed soft round copper wire.
2) Insulation Materials: high density polyethylene or polypropylene, marked in accordance with standard insulated wire color.
3) insulated wire: twisted pairs of insulated wires of two different colors to different pitch and with specified color combinations to identify the pair.
4) cable core structure: 1 pairs as the basic unit of more than 25 on the cable according to the combination of units, each unit with the provisions chromatography unit tie around the bar, in order to identify the different units.
5) The cable core package with: tape wrapped with polyester film.
6) jacket: blue, low-density polyethylene. You can also double-sheathed communication cables.
7) identification and length of the cable tag: cable outer surface of the permanent identification mark, marked at intervals of not more than 1m mark include: wire diameter, wire number, cable type, manufacturer plant name and year of manufacture, length, tag the outer surface, but in the marking to staggered intervals not greater than 1m mark. Mine communication cable with full chromatography insulation, aluminum integrated sheath (ie, longitudinally of the cable, shielded ribbon with jacket bonded into one to form a seal protection layer) with excellent electrical performance, and easy construction.
