This red stripe to be helical for cables with conductor sizes from 0,25 mm2(code 002) to 5 mm2(code 050) and helical or length wise for cables with conductors sizes from 9 mm2(code 090) to 68 mm2(code 680).
26、 In order to allow a legible UV marking, the width of the stripe shall be between 0,3 mm and 0,5 mm. For multicore cable without jacket, each core shall be marked with its own designation.

28、ntification and marking of cables by the manufacturer shall be in accordance with EN 2234. As the designation required for orders is generally too long for use in electrical drawings, a shorter cross designation (without colour information) is given by the AECMA TR 6058 plus the corresponding AWG. T
