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.
Application
Humidity sensor, as an important chemical sensor, which is widely used in fields of warehousing, industry production, and process control, environmental monitoring, home appliances and meteorology etc.
