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).
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.
