LiYY data cables have a small outer diameter despite a high number of conductors. They feature a conductor color code according to DIN 47100, but without color repetition. The stranded conductors are made from bare copper wires, with conductor insulation and outer sheath made of PVC, and the conductors are twisted in layers. They are flame-retardant according to IEC 60332-1 and are in pebble gray (RAL 7032). These are control and signal cables for electronic computing systems, electronic control and regulation devices, office machines, scales, etc.
