Product description

Polythene insulated jelly filled, un-armored telecommunication cables (10 to 2400 pairs with conductorsÆ dia of 0.4mm, 0.5mm, 0.6mm and 0.9mm) are manufactured on pakistan telecommunication company specifications lw-33 with reference to various international standards and specifications. Premier cables offers a wide range of telephone cables.

Application
This cable is usually used for direct buried applications for distribution in the exchange areas as local network and interexchange applications. It is a cable with solid polyethylene insulated unit twin jelly filled construction.

Construction
Conductor:
Solid annealed copperith conductor sizes of 0.4 & 0.6mm.
Insulation:
Colored high molecular weight solid high density polyethylene.
Color coding:
Cables are fully color coded in accordance with pic even count color code.
Twining/pairing:
Two colored insulated conductors are uniformly twisted together to form a pair. Varying lay length is designed to minimize the cross talk and capacitance unbalance.
Stranding / cabling:
Twisted pairs are assembled into unit of 25 pairs. When desired for lay-up reason, the units are divided into two or more sub-units, which are bind with durably colored polyethylene tapes to form a compact and circular cable.
Filling compound:
The water resistant filling compound is applied to the air space within the cable core.
Core covering:
A non-hygroscopic and dielectric polyester tape and water blocking tape are applied helically having a suitable overlap.
Flooding compound:
Sufficient flooding compound is applied between the core wrap and shield.
