Electrical Characteristics at 20℃Conductors: Solid Annealed copper, 1.4 mm nominal diameter (0.6 mm for the auxiliary pair).
Insulation: Polyethylene.
Cabling Element: Two insulated conductors are twisted together to form a pair.
Stranding: Pairs are helically stranded to get the cable core.
Core Wrapping: Plastic tape(s) with overlapping.
Inner Sheath: Low density polyethylene.
Moisture Barrier: Copolymer coated laminated aluminium tape.
Intermediate Sheath: LSZH fi re retardant compound. PE or PVC option can be offered upon request.
Mechanical Protection: Two helically applied steel tapes.
Outer Sheath: LSZH fi re retardant compound. PE or PVC option can be offered upon request.
