X-VOLT HEPRZ1 Cu / AL cable design
Conductor
Aluminium or copper conductor, class 2, based on EN 60228 and IEC 60228.
Internal semiconductor
Screen over the conductor, made of thermosetting semiconductor material.
Insulation
High module ethylene propylene rubber (HEPR), in dry atmosphere catenary tube, through a triple layer extrusion process. Lead-Free version available on request.
External semiconductor
Screen over the insulation, made of thermosetting and strippable semiconductor material.
Metallic screen
Screen of copper wires and copper tape, with a minimum cross-section of 16m2.
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).
(Filling)
(Possible, depending on the configurations).
Outer sheath
Outer sheath of halogen-free polyolefin, red colour.
X-VOLT HEPRZ1 Cu/AL halogen-free polyolefin, red colour.
X-VOLT HEPRZ1 Cu/AL (S) version is fire-retardant and halogen-free polyolefin, red colour with two grey bands.
X-VOLT HEPRZ1 Cu/AL (AS) version is fire-retardant and halogen-free polyolefin, red colour with two green bands.
This cable is available in Cu or AL version.
Steel tape and steel wire armour configuration is also available.
