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,
28、each core shall be marked with its own designation. The colour of stripes is given in Table 2.

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. This shorter designation shall
