Electric cables - Low voltage energy cables of rated voltages up to and including 450/750 V (U0/U) -- Part 2-81: Cables for general applications - Cables with crosslinked elastomeric covering for arc welding
This European Standard applies to single core, crosslinked elastomer covered arc welding cables. The cables are of rated voltage U0/U 100/100 V. The cables are intended for connections between the welding power source and the electrode holder and the work piece. Two types of cable are included, with respectively Class D and Class E conductors. These conductors are more flexible than Class 6 to EN 60228, with Class E having the greater flexibility. The maximum conductor operating temperature for each of the cables in this standard is 85 °C. NOTE HD 516 contains extensive guidance on the safe use of cables in this standard, and gives specific current ratings and volt drop data. This EN 50525-2-81 should be read in conjunction with EN 50525-1, which specifies general requirements.
