BS EN 50525-2-31:2011

Electric cables. Low voltage energy cables of rated voltages up to and including 450/750 V (U0/U). Cables for general applications. Single core non-sheathed cables with thermoplastic PVC insulation | Status: Confirmed, Current

1 Scope 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.
