International Cables Co.

Construction:

Bare copper conductor ,diameter 0.4 mm , 0.5 mm , 0.6 mm or For cable over 100 pairs , the needed units of 50pairs or 100 pairs
0.9 mm , is covered with PE Foam-skin insulation . are twisted together to form the cable core , which is fully filled with
petroleum jelly , than wrapped by one or two polyester tapes .
Each 4 conductors are twisted to form star quad , the quads are
identified by its conductor insulation color . The insulated conduc- A red color helix binder marks the tracer sub unit of the cable or
tors are identified by colors coded and black ring markers . The every main unit as well as the tracer main unit in each layer of the
Basic colors of 4 conductors insulation of each star quad of the cable core, the other sub units or main units are marked by white
basic 5 quads sub unit are red ,green , gray ,yellow and white . color helix binder .

Each 5 quads , in sequence and of color coding ,are twisted to One laminated aluminum tape is longitudinally applied over the
form 10 pairs sub unit , the sub units are stranded together to cable core and an outer sheath of black PE which is both UV and
form cable or main units of 50 or 100 pairs . stress – crack resistant is applied over the shielding.
