Bibliography

Pertains to flexible cables, insulated with crosslinked elastomeric compound, and sheathed with either crosslinked elastomeric compound or thermoplastic polyurethane (TPU).

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.
