2, 3, 3.5 and 4 core, armoured or unarmoured, 650/1100 V

XLPE Multicore Aluminium Power Cables

The aluminium equivalent of the multicore range — substantially lighter and lower cost for the same duty, at one or two sizes larger. The usual choice for distribution feeders and long runs where weight and price matter more than cross-section.

IS 7098 Part 1 650/1100 V AC / 1500 V DC to earth 2, 3, 3.5 and 4 core, 4 mm² to 630 mm²

XLPE insulation — 90 °C continuous, 250 °C short circuit
Roughly a third the weight of the copper equivalent
Galvanised steel flat strip or round wire armour to IS 3975
PVC Type ST2 inner and outer sheath, FRLS / FR / LSZH options
Reduced neutral on the 3.5 core range
