Construction
Conductors
                          Solid Annealed copper, 0.9 or 1.4 mm nominal diameter.
Insulation
                          Solid polyethylene.
Cabling Element
                          Four insulated conductors are twisted together to form a quad.
Stranding
                          Quads are helically stranded in concentric layers. Cables from 7 quads on, have two extra conductors of 0.5mm with perforated insulation (surveillance conductors).
Core Wrapping
                            Plastic tape(s) with overlapping.
IMoisture Barrier
                          One laminated sheath made of aluminium tape (0.15mm) coated with PE-Copolymer on at least one side is applied with longitudinally overlap.
Inner Sheath
Low density polyethylene.
Electromagnetic Shield
                            One helically applied steel tape (0.2-0.3mm) or two helically applied steel tapes (0.1mm).
Outer Sheath
Low density polyethylene.
