 Application： |
|
|
| Designed to use in ducts also can be directly buried into ground. Cables having 0.4 and 0.5 mm conductor diameter are used for distribution networks and cables having 0.6 and 0.9 mm conductor diameter are used for long distance networks. |
| Construction： |
|
|
Conductor
Solid annealed copper having the diameter of 0.4, 0.5, 0.6 and 0.9 mm.
Insulation
Dual insulation of cellular polyethylene covered with a solid skin layer of medium or high-density polyethylene compound
Cable Assembly
Quads, each having special lay length to minimize crosstalk and capacitance unbalance, are assembled into 10 pair, 50 pair or 100 pair units.
Filling Compound
Water resistant filling compound is applied to air spaces within cable core to provide water- proofnes
Core Covering
A non-hygroscopic dielectric plastic tape having suitable overlap is applied longitudinally or helically over cable core.
Flooding Compound
Sufficient amount of flooding compound is applied between core covering material and screen.
Screen (Shield)
A flat aluminium foil coated with copolymer on both sides is applied longitudinally over core covering as screen.
Outer Jacket (Sheath)
Black linear-low density or medium-density polyethylene compound is extruded over screen.
