BS EN 50525-2-21:2011
This standard BS EN 50525-2-21:2011 Electric cables. Low voltage energy cables of rated voltages up to and including 450/750 V (U0/U) is classified in these ICS categories:
- 29.060.20 Cables
EN 50525-2-21 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 450/750 V.
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 EN 50525-2-21 should be read in conjunction with EN 50525-1, which specifies general requirements.
