Product Name:
HYA copper conductor solid core polyolefin insulation to block the influx layer polyethylene sets of local telecommunication cables

Production Standard:
YD/T322-1996

Structural features:
HYA local telecommunication cables using all chromatographic insulation, aluminum integrated sheath (ie, longitudinally of the cable, shielded ribbon with jacket bonded into one layer form a seal retainer), with excellent electrical performance, and easy construction;

Product Use:
The HYA type telephone cable can be used for the communication lines of the towns, peri-, and factories and mines. Mainly used for pipe apply no need to use in the installation of the overhead hanging wire support.

Manufacturer:
The first branch of the Tianjin Cable Plant

Physical parameters:
(1) Core Material: pure copper

Nominal number: 5-2400

(3) the diameter of the conductor: copper wire diameter of 0.32, 0.40,0.50,0.60,0.70, 0.80, 0.90mm;

(4) Insulation material: high density polyethylene;

Insulated single with extruded insulation material: continuous wire, using 10 standard chromatography in order to identify and to ensure that the electrical performance of the cable;

Insulated wires: a single insulated wire in accordance with the pitch of the twisted pairs to minimize crosstalk and with specified color combinations in order to identify the pair;

7. Cable core structure: the insulation of the single-wire stranded in pairs with the core or unit Stranding core units of different tie yarn, for the construction, maintenance identification. 25 pairs as the basic unit of the 25 lines on the basic unit can be 12 pairs and 13 pairs of the two sub-units, 50 units of super-units from the two 12 and two 13 two sub-units, 100 pairs of super-units consists of four 25 basic units. Each unit is color coded around with a cable of 100 pairs and above plus 1% of the spare pairs, but up to more than 10 pairs;

Cable core package with: cable core is coated with non-hygroscopic, non-oil absorption of the tape;

9 shielded cable: use corrugated (or corrugated) double-sided coated aluminum vertical package in the core of the cable package with lap adhesive on both sides;

Cable sheath: black low density, medium density or high density polyethylene;

Do not mark: the cable outer surface of the print identification mark. Tag: cable type, length, company name and year of manufacture. Marker interval of not more than 1m;

12 other structures: according to applications, user requirements, provide various forms of cables to meet the requirements of a variety of laying environmental conditions.
