(Complies with BT Specifications CW1236/CW1198)

PACW/Cell PE Insulation/PJ Filled/PE Sheathed/Steel Wire Armour/PE Oversheath External Telephone Cable

Application

The cable is designed primarily for direct burial in the outside plant area telecommunications networks. The cable core comprises units of cellular polyethylene insulated twin conductors flooded with petroleum jelly compound with a drop point greater than 80ºC and wrapped with a paper tape. The cable core is covered with a black polyethylene inner sheath. A layer of galvanised steel armour wires is then applied over the sheathed cable and an outer sheath of PE is applied over the armour wires.

Construction

Available as twisted pairs in 25 Pair Units.

Product description

Plain annealed solid copper wire, cellular polyethylene insulation, twisted pairs, petroleum jelly filling, paper core wrap, and black low- density polyethylene sheath. The armour is used as additional protection of telecommunication cables for direct burial.

The jelly-filled cable is armoured with a suitable number of galvanised mild steel wires applied directly over the polyethylene sheath of the cable. The wires comply with BS EN 10257 Part 1 except that the tensile strength is not less than 340 MN/m2 and not greater than 540 MN/ m2. The value of resistivity for the armour is not mandatory. The armoured cable is sheathed overall with PE.
