Jelly filled UG cables
Polyethylene insulated jelly filled Telephone Cables are widely used for primary and Secondary distribution networks. The cables having single jacket are use as duct cables up to 2400 pairs as primary network. Secondary cables are directly buried and may Armoured with additional jacket of a tough weather resistance LDPE Compound.
The cables core are fully filled with gel type hydrocarbon base filling compound having the same dielectric constant and compatible with the insulation and jacketing materials. The cables are manufactured with high-grade materials according to REA & Pakistan Telecommunication Company Limited Specification or customer’s requirement
CONDUCTOR:
Fully annealed high quality solid copper, the conductor sizes are 0.4, 0.5, 0.6 & 0.9 mm.
INSULATION:
Colour high molecular Weight High-Density Polyethylene (HDPE)
PAIRING
Two coloured insulated conductors are uniformly twisted together to form a pair, Varying lay length is designed to minimize the cross talk and capacitance unbalance.
COLOUR CODING
Colour are fully colour coded in accordance with PIC even count colour code
FILLING COMPOUND
The water resistant filling compound is applied to fill the air spaces within the cable core.
CORE COVERING
A non-hygroscopic and dielectrical heat resistant Polyester Tape and Water Blocking Tape are applied helically having a suitable overlap
FLOODING COMPOUND
Gel type hydrocarbon base compound is applied between the core wrap and shield
MOISTURE BARRIER INNER PE SHEATH (INNER JACKET)
An Almunium Tape with Copolymer coating is applied over the cable core & sheath with Black Polyethylene Compound
ARMOUR (OPTIONAL)
A Tin Coated Corrugated Steel Tape is applied longitudinally directly over the Inner Sheath with suitable flooding compound.
JACKET
Black High Molecular Weight Low Density Polyethylene (LDPE)
IDENTIFICATION
An Identification Tape durable marked with the Manufacturer’s Name, year of Manufacturing,Contract Number, Cable size & Type, if required, is placed under the Core Covering Tape. Alternatively, these details may be printed on the outer jacket of cable with length marking.
