Bibliography

EN 50525-2-31 applies to non-sheathed single core cables insulated with thermoplastic (PVC) insulation. The cables are of rated voltages U0/U up to and including 450/750 V. The cables are intended for fixed wiring applications. NOTE 1 Cables rated 450/750 V may be used at 600/1 000 V when this cable is used in fixed installations with mechanical protection, within switchgear and control gear - see HD 516. The maximum conductor operating temperatures for the cables in this standard are 70 °C (V types) and 90 °C (V2 types). NOTE 2 HD 516 contains extensive guidance on the safe use of cables in this standard. This EN 50525-2-31 should be read in conjunction with EN 50525-1, which specifies general requirements.
