Description
Telephone cables from 6 to 2424 pairs, copper conductors from 0.405 to 0.91 mm diameter, solid PE insulation. The pairs are twisted into units of 25 pairs and these are stranded to form the core. The core is filled with a compound of PE petroleum jelly and protected with a moisture barrier sheath. They are used as distribution or connecting cables between areas. The installation may be either in ducts without pressurization or directly buried.
