Self-supporting full-plastic cable (HYAC) : self-supporting full-plastic cable has two kinds of concentric structure and calabash structure. The commonly used HYAC full-plastic cable is calabash structure. Wire: annealed bare copper wire with diameter of, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9; Color the insulation line according to the full chromatographic standard. A single insulated wire is twisted in pairs at different pitch to minimize crosstalk and a specified chromatographic combination is used to identify pairs of wires. Cable core: the cable core structure is based on 25 pairs of cables. More than 25 pairs of cables are assembled according to the unit. Each unit is wrapped with the unit of specified chromatogram to identify different units. More than 100 pairs of cables plus 1% of the reserve pair. Shielding: the shielding layer is made of corrugated metal tape which is wrapped vertically on the outside of the cable core wrap belt and firmly bonded on both sides. The metal strip of the shielding layer is coated with plastic film to facilitate bonding with the sheath to prevent corrosion of the shielding layer. Protective sleeve: protective sleeve is black low density polyethylene, can use double protective sleeve according to the need.

Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.
