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.)

1 mm² = 39.2 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.
