HYAT23 armoured communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and vulnerable to erosion area and design of telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter.
