X-VOLT RHVhMVh 3x Cu +H1 cable design
Copper conductor, class 2, based on EN 60228 and IEC 60228.
Screen over the conductor, made of thermosetting semiconductor material.
Cross-linked polyethylene (XLPE), in dry atmosphere catenary tube, through a triple layer extrusion process.
Screen over the insulation, made of thermosetting and strippable semiconductor material.
Cable conductor identification
The conductors are identified with a tape placed along the cable between the outer semiconductor and the screen. Colours are; brown, green and yellow.
Screen of copper wires and cross-wound of copper tape placed helicoidally. (H1 screen).
The three conductors are wound helicoidally with their screens in contact. Bedding is used to fill the spaces between the conductors to achieve a better cylindrical finish.
The special PVC compound bedding gives a high level of resistance to hydrocarbons and mineral oils.
Galvanized steel wire wrapped helicoidally around the cable and fixed with a counter-wound metal tape.
8. Outer sheath
The special PVC outer sheath compound gives a high level of resistance to hydrocarbons and mineral oils. Red colour.
