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.
