X-VOLT DHZ1 Cu
Conductor:
Annealed electrolytic copper conductor, class 2.
Optionally, with longitudinal sealing (cable type -2OL).
Internal semiconductor:
Screen above the conductor, made of thermosetting semiconductor material.
Insulation:
Ethylene polypropylene rubber (EPR), 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 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. Optionally with grey (S) or green (AS) bands.
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.
Optionally, types (S) and (AS) can be manufactured:
- Halogen-free cable with low smoke emission and no flame propagation. Safety cable (S).
- Halogen-free cable with low smoke emission and no flame propagation. Safety cable (AS)
