110: Type Designation code for power cables

Designation codes (marking) of power cable according to DIN VDE has a below structure with 11 sections. Each section indicates one of the cable specifications.

Power cables with plastic insulation and plastic sheath:

According to DIN VDE 0262, DIN VDE 0263, DIN VDE 0265, DIN VDE 0266, DIN VDE 0267, DIN VDE 0271, DIN VDE 0273 and DIN VDE 0276 part 603, 604, 620, 622 and 626
