It is applicable to the communication lines in the city, in the suburbs and some local regions. area and the relay route. It can be used in overhead and duct. The working temperature is -30+60.
Specificationall types of the HYA type cable(≤1200 pairs) can be provided.
2.Application: It can be used to transmit audio signals and digital signal of the integrated services digital network with the rate of below 2B + D-rate. It can also transmit 2048kbit /s digital signals or the analog signals (below 150KHz).
3.Certification: ISO90012000, TLC.
4.Laying Method: Overhead, duct.
5.Product Structure:
1.Conductor: bare soft-annealed copper wire , the diameter of the copper conductor are:0.40mm,0.50mm0.60mm.
2.Insulation MaterialHigh-density polyethylene or polypropylene, and marking color of the wire is totally accordance with the Chromatography Standards.
3.Insulated wire pair: in order to minimize crosstalk, each wire is twisted into pair in different pitch, and the wire is painted with different colors according to Chromatography Standards to recognize them.
4.Core structureevery 25 pairs are called as a unit, the cable which contains more than 25 pairs is combined on the base of unit. In order to recognize different units, each unit is bundled with the right cable tie according to the Chromatography Standards. The cable which contains more than 100 pairs has 1% prepared pairs, but the prepared pairs are not more than 6.
5.Core wrappingthe cores are wrapped longitudinally or with the core wrapping which is made from polyester membrane tape or other Non-hygroscopic insulation tape.
6.Shieldthe shield layer, which is made from double-sided coated aluminum tape with a thickness of 0.25mm, is on the outside of the core wrapping; the two overlapped sides of the shield layer are put together with the black low density polyethylene jacket.
7.Sheath: black low density (linear low density ) polyethylene.
8.Identification and length makingthe cable surface has a permanent identification mark which says the interval is 1 meter. The content of the mark includes model, specification, manufacture name, year of being made and the length.
