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. 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.
