Cable Construction

Conductors Solid annealed copper, 1.6 mm nominal diameter.
Insulation Solid polyethylene.
Stranding Conductors will be stranded with dielectric fi llers in order to get a circular core shape.
Core Wrapping Plastic tape (s) with overlapping.
Inner Sheath Low density polyethylene.
Screen Aluminium/polyethylene tape longitudinally applied and overlapped.
Drain Wire Tinned copper drain wire.
Intermediate Sheath Low density polyethylene.
Armour Two galvanized steel tapes.
Outer Sheath Low density polyethylene.
