Construction

What it is and what it is for

Low-tension power and control cables with XLPE insulation, laid up and inner-sheathed with PVC tape, then finished with an extruded PVC type ST2 outer sheath. They are rated 650/1100 V and made to IS 7098 (Part 1).

Copper conductors are solid up to 6 sq mm and stranded above. Aluminium conductors are solid up to 10 sq mm and stranded above. Armouring is galvanised steel round wire for smaller multicore cables and galvanised steel strip for larger ones; single-core cables use aluminium wire or strip, because steel armour around a single core heats up.

Every construction can be upgraded: FR-LSH or LSZH sheaths, heat-resistant PVC, tinned conductors, round-wire armour and higher oxygen index compounds are available as options.

  • Main and sub-main feeders
  • Factory and building distribution
  • Street lighting and outdoor runs (armoured)
  • Control and interlock wiring
