AUXILIARY SWA LSNH

7 CORE 2.5 STRANDED XLPE/LSNH/SWA/LSNH

These cables are designed to be used in installations where smoke and acid gas emission would pose a major hazard in the event of a fire.

Auxiliary Steel Wire Armoured cables are predominantly used for industrial wiring and signalling.

They are designed to be used in industrial areas, areas with higher risk of mechanical stress/damage, in and around buildings and other similar environments.

These cables are designed to be installed in air, clipped to surface, on cable tray/ladder work, embedded in concrete and buried direct or in ducting underground.

Multicore Loading
In practice, the majority of cores in a multicore control cable of 7 cores and above carry only small or intermittent current and a current rating based on the assumption that all cores are equally loaded is quite unrealistic. In most cases only two cores, the live and neutral feed cores are likely to approach the maximum permitted loading. The current rating for twin core cable can therefore be used in these cables.
Where more than two cores are known to carry an appreciable current, the multiplying factors applicable to the two core ratings are given below. The normal current rating for twin cable may also be used in cases where the number of cores carrying appreciable current does not exceed the square root of the total number of cores in the cable.
