Cables (ICS 29.060.20)

ELECTRIC CABLES - THERMOSETTING INSULATED, ARMOURED CABLES OF RATED VOLTAGES OF 600/1000 V AND 1900/3300 V FOR FIXED INSTALLATIONS (7 page(s), in English)

This standard specifies the compulsory requirements for the construction and performance of thermosetting insulated, armoured electric cables for voltages of 600/1000 V and 1900/3300 V.

This standard is applicable to electric cables for use in fixed installations in industrial areas, buildings or similar applications, of the following types:

1.    600/1000 V cables, wire armoured and oversheathed, having single-core, two-, three-, four- and five-core stranded copper conductor;

2.    600/1000 V multicore auxiliary cables, wire armoured and oversheathed, stranded copper conductor; and

3.    1900/3300 V cables, wire armoured and oversheathed, having single-core or three-core stranded copper conductor.

This standard is applicable to electric cables that are designed for a maximum sustained conductor temperature of 90°C and for a maximum short-circuit conductor temperature of 250°C (for a maximum of 5 s).
