Description of In-city communication cable HYA

1) 0.5 mm pure copper conductor

2) HDPE insulation, The insulated lines are separated by 10 colors according to the standard requirements.

3) Insulated single line: solid polyolefin insulated single line. The insulated lines are separated by 10 colors according to the standard requirements.
4.) Insulated pair lines: wring two single lines together with different pitches according to the chromatogram composition that required.
5). Cable core cover belts: the cable core is covered by polyester film or film belts, and wrapped steadily by the polyester yarn.
6). Shielding: usually use Aluminum belts.
7). Layer: the shielding layer is covered by the low density polyethlene film which contains the 2.5±0.5% carbon black in it, thus formed a good damproof layer.
8). ADSS Cable: add an aerial cable on the base of HYA, can be overhead.
9). Features: aerial cable.
10). Applications: voice communication.

11) Packing: 1,000 meters / box or according to the buyer's requirement
