DESCRIPTION AND APPLICATION 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. CONSTRUCTION • Conductors: Annealed copper, diameters of 0.40, 0.51, 0.64 and 0.91 mm. • Insulation: Solid HDPE. • Cabling elements: Pairs. • Lay-up: Up to 26 pairs into layers. Cables over 26 pairs in units of 25 pairs. • Filling compound: Petroleum jelly. • Core wrapping. Dielectric tape longitudinally applied with overlap. • Screen. Longitudinal aluminium tape coated with PE copolymer applied with overlap and bonded to the outer PE sheath. • Sheath: Black PE, UV resistant. • Sheath marking: The outer sheath shall be marked at regular intervals with the following information: o Name of Manufacturer / year / Length markings o Other type of markings is also possible according to the customer ELECTRICAL CHARACTERISTICS (20°C) Maximum conductor Resistance (Q/km) Resistance unbalance (%) 100x(Rmax-Rmin)/(Rmin + Rmax) Minimum insulation resistance (MQxkm, 15°C, 500 V) Mutual capacitance (nF/km, 800 Hz) Capacitance unbalance (pF/km, 800 Hz) Pair-pair Pair-earth < 45rms (<12 pairs) / < 145 (>12 pairs) Average: < 574 (>12 pairs) / maximum: < 2625 Dielectric strength (Vdc, 3 s) conductor - conductor conductor - screen All drawings, designs, specifications and particulars of weights, dimensions, etc. in this documentation are only indicative and must not be considered contractual.
