EN 50382-2 Single core silicone rubber insulated cables – Scope
Part 2 of EN 50382 specifies requirements for, and constructions and dimensions of, single core cables of the following types and voltage ratings:
- 1.8/3 kV unscreened, unsheathed with or without textile braid (1.5mm2 to 400mm2);
- 1.8/3 kV unscreened, sheathed (1.5mm2 to 400mm2);
- 3.6/6 kV unscreened, unsheathed with or without textile braid (2.5mm2 to 400mm2);
- 3.6/6 kV unscreened, sheathed (2.5mm2 to 400mm2).
All cables have class 5 or class 6 tinned or plain copper conductors to EN 60228, halogen-free insulation and where applicable halogen-free sheath. They are for use in railway rolling stock as fixed wiring, or wiring where limited flexing in operation is encountered. The requirements provide for a continuous conductor temperature not exceeding 120℃or 150℃ and a maximum temperature for short circuit conditions of
either 250℃or 350℃based on a duration of 5 s. When the insulating compounds and sheath specified in this standard which are thermally capable of operating at 150℃ are used with tinned conductors, the maximum operating temperature is limited to 120℃ and, for the same technical reason, the maximum short circuit temperature is limited to 250℃. The choice of sheath may also limit the maximum operating temperature to 120℃.
A textile braid may be included in the insulation or applied at its surface to unsheathed cables.
