2 PAIR LEAD-IN CABLES
Lead In Cable 2 Pair is used between the terminal box and the customer’s premises. These cables are based on Pakistan Telecommunication Company Limited specification.
Fully annealed high-quality solid copper conductor size 0.5mm
Colour high Molecular Weight solid high-Density Polyethylene compound
The insulated conductors twisted together into colour coded pair:
Two colored insulated conductors are uniformly twisted together to form pair. The twisted length being specially designed to minimize the cross talk and capacitance unbalance.
Inner Sheath of Polyethylene is used to fill up spaces between insulated conductors for the purpose of water blocking and give the core a round cross-section.
The armouring shall consist of Aluminum Tape.
Black High Molecular Weight Low-Density Polyethylene Compound
The manufacturer’s Name year of Manufacturing and cable size shall be printed on the outer sheath of cable with Length Marking.
