Conductor:
Electrolytic compacted aluminium conductor, class 2.
Optionally, with longitudinal sealing (cable type -2OL).
Internal semiconductor:
Screen above the conductor, made of thermosetting semiconductor material.
Insulation:
High module ethylene propylene rubber (HEPR), 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
Separator:
Polyester tape completely covering the screen to facilitate the
stripping of the outer sheath. Optionally, substituted by hygroscopic
strap (cables with longitudinal sealing type -OL and -2OL).
External sheath:
External sheath of fire-retardant and halogen-free polyolefin, red colour with two grey bands. (for S type)
Applications:
Cable for fixed installations. Suitable for the transmission and
distribution of energy in a medium voltage network. Can be used indoors, outdoors and in underground applications.
Halogen-free cable with low smoke emission and no flame propagation properties, safety cable (S).
