MEDIUM VOLTAGE 12/20 kV 18/30 kV

HD 620-9-E Reference Norm

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:
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)
