25、g Outer insulation shall be white with a red stripe to indicate fire-resistant construction. 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. The colour of stripes is given in Table 2. EN 2346-002:20066 Table 2 Number of cores Colour of stripe 1 Red 2 Re

28、tification 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. Th
29、is shorter designation shall be used for identification and marking as the following example: EXAMPLE Designation EN2346-003A006 Cross reference DL 20 Reference to EN standard cable 3 mandatory spaces Type code Size code Manufacturer country code Manufacturer code Year of manufacturing EN DL 20 FRF9
