Polyethylene Unit Twin Cable with Moisture Barrier Sheath
CP-FS-HUT-LAP
This high quality insulated cable used subscribers distribution. Featuring: The cable is insulated full color coding with an extruded foam-skin insulating high-density polyethylene compound in the air space to water resistant filling compound.
‧ Conductor：Solid annealed copper wire size 0.4、0.5、0.63mm。
‧ Insulation：Foam-skin polyethylene
‧Twinning：Two insulated conductor are twisted into a pair.
‧Cable Formation：
Twisted pairs are assembled to form a substantially cylindrical group of 25 pairs (called unit).When desired for lay-up reasons; the units are divided into two or more sub-unit.
If the cable size up to 50 pairs and including 50pairs,Cable will consist of 10 pairs stranded together to form a compact bunch, which can be further divided into two sub-units of 5 pairs.
