HEPRZ1 Aluminum EPR insulation medium voltage power cable
HEPRZ1 Aluminum EPR insulation medium voltage power cable with HEPR insulation and halogen-free. Due to the special features, these cables can be used in fixed installations indoors, outdoors or underground.
HEPRZ1 Aluminum EPR insulation medium voltage power cable construction
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.
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 halogen-free polyolefin, red colour.
