  • description

This product is copper core polyethylene insulated communications cables in the city, produced according to YD / T322-2013 standards, mainly used for signal transmission between equipment, as well as rail transit, cableway and other projects, with complete specifications, the structure of diversified features. This series of products include filled and metal armor structure, with anti-aging, waterproof, anti-external stress and other characteristics, with a small attenuation, stable impedance, high shielding effect of electrical properties. It retains its excellent electrical and mechanical properties in a complex environment with more reliable performance than conventional cables.

HYA-type local telephone cable can be used for urban, suburban and factories and mines in the communication lines. Mainly used for pipe laying, overhead installation need to use hanging wire support HYAC. Buried in the outdoor use of the need to oil-filled waterproof moisture HYAT, buried directly use the need steel belt armor HYAT22. Structure – Henan Xin Bo Special Cable Co., Ltd.

  • Wire: Solid annealed copper wire. Copper wire diameter: 0.4/0.5/0.6/0.7/0.8/0.9mm.
  • Insulation: High-density polyethylene, and in accordance with the standards of the whole chromatogram indicate the color of the insulated wire.
  • Insulated wire pairs: Twist pairs of individual insulated wires at different pitches to minimize crosstalk and use the specified chromatographic combination to identify pairs.
  • Cable core structure: 25 pairs of basic units, 25 pairs of basic units can also be 12 pairs and 13 pairs of 2 subunits, 50 units of super units by two 12 pairs and two 13 pairs of two sub-units 100 superelements consist of four 25 basic units. Each unit is supplied with 100% of the cable ties plus 1% of the spare wire pairs, but not more than 10 pairs, for the tapes of the specified chromatography.
  • Core package tape: with polyester film with vertical cable core.
  • Shielding: Plastic coated on one side of an aluminum strip (aluminum strip thickness 0.15mm), the aluminum strip is wrapped in the longitudinal direction on the core, the strip should overlap.
  • Jacket: black low-density or medium-density polyethylene.
