Outdoor Drop Cat5e Telephone Cable Wire 500P With Bare Copper Conductor
Feature different strand lay-length, keeping good NEXT and FEXT, anti-electromagnetic disturbimprovement .
Structure bare copper, PE insulation, FR PVC/LSOH PVC jacket, twinning structure, flexible added, easily cabling.
Telephone cable trunk transmission .
copper core solid polyolefin insulated aluminum-plastic bond sheath non-filled city communications cables in accordance with the national standard and the Ministry of Posts and Telecommunications standard production.
use
local telephone cable can be used in the towns, suburbs and factories and mines in the communication lines. Mainly used for pipe laying, overhead installation need to use hanging wire support. Buried in the outdoor use of oil-filled to be waterproof and moisture-resistant, direct use of buried steel belt armor.
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.
8. load bearing line:Galvanized steel, high-quality steel,more safety and convenient.
