EN50525-2-21 applies to flexible cables, insulated with crosslinked elastomeric compound, and sheathed with either crosslinked elastomeric compound or thermoplastic polyurethane (TPU).
The cables are of rated voltages U0/U up to and including 450/750V.
The cables are intended for a variety of applications where appliances or equipment, including heavy industrial equipment, require a flexible connection to the power supply.
The maximum conductor operating temperatures for the cables in this standard are 60°C (R types), 90°C (B types) and 110°C (G types).
The following particular cable types are included:
General purpose cables (RR and RN types);
Water-resistant cables (RN8 types);
General purpose cables (BB and BN4 types);
TPU sheathed cables (BQ types);
Heat resistant cables (GG types)
NOTE HD 516 contains extensive guidance on the safe use of cables in this standard.
This EN50525-2-21 should be read in conjunction with EN50525-1, which specifies general requirements.
