FLEXIBLE SINGLE & MULTICORE CABLE

PVC compound insulated single core and multi core flexible cables have a wide range of application in machine tools, appliances, control panels, machinery and industries of every nature.

The conductors, drawn from 99.97% bright electrolytic grade copper with more than 100% conductivity, are annealed and bunched together. The conductors are insulated with a PVC compound with high insulation resistance and dielectric strength, formulated and manufactured in-house.

In case of multicore cables, the insulated cores are laid up to form the core assembly. The inner cores are coded for ease of identification as per National/International coding practices. The sheathing is provided with a specially formulated PVC compound to facilitate not only ease in stripping but also to withstand mechanical abrasion while in use. These PVC compounds used for insulation and sheathing have a high oxygen and temperature index. These properties help in restricting the spread of fire even at very high temperatures.

The single core and multicore sheathed cables are manufactured as per IS 694 : 1990, in sizes from 0.5 sq. mm. to 50 sq. mm. in single core, and in sizes 0.5 sq.mm. to 4.0 sq. mm. upto 5 cores. These sizes carry the prestigious ISI mark and are duly approved by FIA/TAC. The rest of the sizes generally conform to IS 694 : 1990. Cables as per BS 6004 and BS 6500 are also available for the export market. Special purpose cables in screened construction can also be made available.
