The cable is designed primarily for interconnection between buildings within a telecommunication network where the cable is used both inside the building and outside in ducts between the buildings. The cable replaces the traditional PVC sheathed cable inside the building and the Polyethylene sheathed cable outside, making the need to joint at building entries redundant. The design includes a metallic moisture barrier bonded to the sheath to combat the ingress of moisture vapour and the sheath is a low smoke non-halogenated polymer, which imparts a high degree of flame retardancy to the cable. The cable core is similar to BT Specification CW 1308.
Twisted pairs in 10 Pair Units. The pair range is 10 – 100. Number Pairs Conductor Diameter (mm) Minimum Radial Insulation (mm) Maximum Insulated Diameter (mm) Unit Size/ Make-up Minimum Sheath Radial (mm) Maximum
Plain annealed solid copper wire; PVC insulation with the required number of pairs assembled in 20 pair units. A polyester tape is applied over the cable core followed by a Polyethylene/Aluminium Laminate moisture barrier, which is bonded to the Low Smoke Non-Halogenated (LSZH) sheath. An optional 1.38mm diameter PVC insulated Earth Wire may be included within the cable core on request.
