Abstract

1 Scope This document specifies requirements for, and constructions and dimensions of, multicore and multipair cables rated voltage U 0 /U : 300/500 V, of the following types:

— unscreened, sheathed for either exposed or protected wiring (0,5 mm 2 to 2,5 mm 2 , number of cores from 2 to 48);

— screened, sheathed for either exposed or protected wiring (0,5 mm 2 to 2,5 mm 2 , number of cores from 2 to 8);

— unscreened, sheathed for either exposed or protected wiring (0,5 mm 2 to 1,5 mm 2 , number of screened pairs of cores from 2 to 7).

— screened, sheathed for either exposed or protected wiring (0,5 mm 2 to 1,5 mm 2 , number of unscreened pairs of cores from 2 to 7).

All cables have stranded tinned copper conductors, halogen-free, thin wall thickness insulation and standard wall thickness sheath. Cable types are specified for use in exposed situations (Class E), and for protected situations (Class P). They are for use in railway rolling stock as fixed wiring or wiring where limited flexing in operation is encountered. These cables are rated for occasional thermal stresses causing ageing equivalent to continuous operational life at a temperature of 90 °C. For standard cables this is ...
