DESIGN
Conductor:
Electrolytic compacted aluminium conductor, class 2.
Optionally, with longitudinal sealing (cable type -2OL)
Internal semiconductor:
Screen over the conductor, made of thermosetting semiconductor material
Insulation:
High module ethylene propylene rubber (HEPR), cross-linked in dry nitrogen
atmosphere.
External semiconductor:
Screen over the insulation, made of thermosetting and strippable semiconductor
material.
Copper screen:
Screen of Cu wires and 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 tape (cables with longitudinal
sealing, type -OL and -2OL)
External sheath:
External sheath of halogen-free polyolefin, red colour
APPLICATIONS
Cable for fixed installations. Suitable for the transmission and distribution of electricity in a medium voltage network, halogen free. Can be used indoors, outdoors
and in underground applications.
