Conductor:
Electrolytic aluminium conductor, class 2. Optionally, with longitudinal sealing (cable type -2OL).

Internal semiconductor:
Screen above the conductor, made of thermosetting semiconductor material.

Insulation:
Cross-linked polyethylene (XLPE), cross-linked in dry nitrogen atmosphere.

External semiconductor:
Screen above the insulation. Made of thermosetting and strippable semiconductor material.

Copper screen:
Screen of Cu wires and cross-wound of Cu tape, with a minimum cross-section of 16 mm2.

Longitudinal sealing:
Hygroscopic tape completely covering the screen (cable type –OL and -2OL).

Filling or separator:
