SELF SUPPORTING AERIAL TELEPHONE CABLE
These cables are used for junction network is exchange area for Aerial installation. These cables are generally based on REA and Pakistan Telecommunication Company Limited Specification.
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)
COLOUR CODING
Colour are fully colour coded in accordance with PIC even count colour code
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.
STRANDING UNITING
Twisted pairs are assembled into unit of 12, 13, 25, 50, 100 pairs, when desired for lay-up reason the units are divided into two
or more sub-units, which are bind with durably coloured polyethylene Tapes to from a compact and circular cable.
CORE COVERING
The core is wrapped with non-hygroscopic and dielectric polyester Tape with suitable overlap
JACKET
Black High Molecular Weight Low Density Polyethylene (LDPE)
SUSPENSION STRAND
Extra high strength of galvanized steel wires strands use as a support strand to from the shape as defined
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.
