|
Application: |
|
|
| Designed to use in ducts. 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
Five quads, each having special lay length to minimize crosstalk and capacitance unbalance, are assembled into 10 pair units. Super units having 50 pairs or 100 pairs or cable core are assemled in these units.
Filling Compound
Water resistant filling compound is stuffed into spaces within cable core to provide water- proofness.
Core Covering
A non-hygroscopic dielectric plastic tape having suitable overlap is applied longitudinally or helically over cable core.
Inner Jacket
(Inner Sheath)
Black linear low density or medium density polyethylene compound (acc. to ASTM D 1248) is extruded over screen.
Flooding Compound
Sufficient amount of flooding compound is applied between inner jacket and screen.
Screen (Shield)
Coated with polymer on both sides, flat aluminium foil is applied longitudinally over inner jacket as screen.
Outer Jacket (Sheath)
Black linear-low density or medium-density polyethylene compound is extruded over screen.
