Design- Conductor
Tinned copper wire, 0.9 or 1.4 mm nominal diameter - Insulation
Solid polyethylene - Twinning
Two insulated conductors are twisted together to form a pair - Stranding
Pairs are helically stranded in concentric layers. - Longitudinal watetightness
Cable core interstices are filled with a low-permitivity compound - Core wrapping
Plastic tape(s) with overlapping - Moisture barrier
One laminated aluminium-copolymer tape, longitudinally applied with overlap - Inner sheath
HFFRLS compound - Electrostatic shield
One layer of helically applied copper wires - Electromagnetic shield
Two helically applied steel tapes - Outer sheath
