Armoured communication cable - armoured phone cable
Armoured communication cables mechanical protection layer can be added to any structure of the cable, to increase the mechanical strength of the cable, improve the anti erosion ability, is designed for susceptible to mechanical damage and erosion prone areas of telephone cable. You can use any kind of way of laying, more suitable for rock area laying buried.
Armoured communication cable structure:
1, basic cable: any single or double sheath structure is devided into filled and non-filled cables.
2, sheathed communication cables mechanical protection layer: 53 type uses 0.15mm thickness corrugated steel, longitudinal coating on basic cable, on both sides of the lap. The surface of the steel strip is plastic processing, to prevent corrosion and moisture intrusion. 22, 23 type use double steel belt wrap and has similar performance.
3, armored communication cable jacket: black high molecular weight and low density polyethylene or polyvinyl chloride sheath. Sheath thickness can be determined by the outer diameter of the basic cable.
4, identification and length tag: the cable appearance has a permanent identification mark, mark interval is not greater than 1m.
5, sheathed communication cables labeled content has: wire diameter, wire quantity, cable type, length, manufacturing factory name and year of manufacture.
6, armored communication cable electrical characteristics: meets all requirements of basic electrical cables.
