Cable Construction

Bare copper stranded 7 wire conductor.

Conductor make-up for

 0.22 mm² = 7 x 0.20 mm

 0.34 mm² = 7 x 0.25 mm

 0.5 mm² = 7 x 0.30 mm

 0.75 mm² = 7 x 0.37 mm

 1 mm² = 7 x 0.43 mm

Conductor Resistance (loop) at 20°C

 0.22 mm² = 186 Ω/km (max.)

 0.34 mm² = 115 Ω/km (max.)

 0.5 mm² = 78.5 Ω/km (max.)

 0.75 mm² = 58 Ω/km (max.)

•  Core colours as per DIN 47100 (Refer table no. 2-1 of appendix)
•  PiMF : (pair in metal foil) cores twisted in pairs, foil wrapped plastic coated aluminium foil and copper drain-wire tinned,
•  100% coverage.
•  PiMFs are stranded in layer.
•  Core wrapping with plastic tapes.
•  Overall copper screened braiding, 85 % coverage
•  Special PVC outer sheath TM2, to EN 50363-4.1.
•  Colour grey (RAL 7032).

Properties

PVC self-extinguishing and flame retardant according to EN 60332-1-2. The twisted-pair lay-up prevents electrical unbalances within the cable and this thus effectively suppresses cross-talking effects.
