SELF SUPPORTING AERIAL 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.
Fully annealed high quality solid copper, the conductor sizes are 0.4, 0.5, 0.6 & 0.9 mm.
Colour high molecular Weight High-Density Polyethylene (HDPE)
Colour are fully colour coded in accordance with PIC even count colour code.
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.
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.
The core is wrapped with non-hygroscopic and dielectric polyester Tape with suitable overlap.
Extra high strength of galvanized steel wires strands use as a support strand to from the shape as defined in the figure blew.
Black High Molecular Weight Low Density Polyethylene (LDPE)
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.
