Construction

Conductors
Soft annealed solid copper, 1.4 mm nominal diameter.

Insulation
PE insulation.

Cabling Element
Four insulated conductors are twisted together to form a quad.

Stranding
Quads are helically stranded in concentric layers.

Core Wrapping
Two or more layers of plastic tape(s) with overlapping.

Screen
Copper tapes with overlap (protection against interference).

Inner Sheath
LSZH sheath, coloured green.

Armour
Two layers steel tape (0.8mm thick).

Outer Sheath
LSZH sheath, coloured green.
