These cables are designed for use in underground, under-water or on wet surface. These cables are manufactured with conductor using annealed exposed copper wires of electrolytic position, bunched correctly to confirm required flexibility.

The cover with uniform thickness of Heat and Moisture Resistant type PVC compound formulated and manufactured in-house, is extruded over these coloured cores in a flat formation.
