underground type 0.4/0.5mm 10 pairs communication cable
Structure:
1.Conductor: Solid annealed copper wire. Copper wire diameter: 0.4, 0.5, 0.6, 0.7 mm.
2.Insulation: High-density polyethylene, color-coded according to the standards of the whole chromatogram
3.Insulated wire pairs: pairs of single insulated wires are paired at different pitches to minimize crosstalk and use the specified chromatographic combination to identify pairs.
4.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 The super unit consists 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.
5.Cable core tape: with polyester film with vertical cable core.
6.Shielding: Plastic coated on one side of an aluminum tape (aluminum tape thickness 0.25mm), the aluminum tape is wrapped in the longitudinal direction on the cable core, the tapes should overlap.
7.Jacket: black low density or medium density polyethylene.
