This cable is used for junction network in exchange area for Aerial Installation. This cable is generally based on Specification REA PE-22 and as per latest specifications of Pakistan Telecommunication Company Limited, Islamabad, it is the best solution to overcome right of way (ROW) issues.
Construction & Key Features
Solid Annealed Copper, the conductor sizes are 0.5, 0.6 and 0.9 mm.
Colored High Molecular Weight Solid High-Density Polyethylene.
C- Color Coding
Cable are fully color coded in accordance with PIC even count color code.
D- Twining /Pairing
Two colored insulated conductors are uniformly twisted together to form a pair. The twist length being specially designed to minimize the cross talk and capacitance unbalance.
Twisted pairs are assembled to form a substantially cylindrical group of 25 pairs called unit. When desired for lay-up reason, the units are divided into two or more sub-units, which are bind with durably colored polyethylene tapes and cabled to complete cable core.
F- Core covering
A Non-Hygroscopic and Dielectric Polyester Tape is applied longitudinally or helically having a suitable overlap.
Electrically continuous, Aluminum Tape is applied longitudinally with an overlap. Tape is coated both sides with a co-polymer P.E. Providing corrosion resistance and a complete / firm bond to the Jacket inhibiting the entrance of moisture into the cable core.
H- Suspension Strand
Extra high strength grade and galvanized steel stranded wire use as a Support Strand.
A plastic tape, durably marked with the manufacturers name, year of manufacture and cable size, if required, is placed under the core covering. Alternatively, these details may be printed on the outer jacket of cable.
Black High Molecular weight low-density polyethylene compound.
