5. General make-up of the cable
5.1 Conductor
Electrolytic annealed aluminum conductor, class 2 according to EN 60228 / IEC 60228.
Optionally, hygroscopic tapes can be applied to achieve longitudinal water-tightness
on the conductor (cable type -2OL)
5.2 Inner semi-conducting screen
Cross-linked semiconductor screen applied over the conductor in a triple-extrusion process.
5.3 Insulation
Cross-linked polyethylene insulation, type DIX-3 according to HD 620-1 and type XLPE
according to IEC 60502-2; natural color. Cross-linked in catenary line with nitrogen
atmosphere.
5.4 Outer semi-conducting screen
Cross-linked semiconductor screen applied over insulation in a triple-extrusion process.
Strippable.
Optionally, under customer requests, it can be supplied non-strippable (bonded to insulation).
5.5 Metalic screen
The metallic screen made with Cu wires and Cu binder tape, applied over the outer semiconducting
layer. 
5.6 Water blocking
The hygroscopic tape is applied over the metallic screen.
5.7 Outer sheath
Polyolefine outer sheath, type DMZ1 according to HD 620-1 and type ST7 according to IEC
60502-2; red color.
