HVDC XLPE- crosslinked polyethylene
We introduced the world’s first extruded HVDC XLPE cable system in 1998 and since then have installed and commissioned thousands of kilometres. An extruded HVDC cable has a copper or aluminium conductor and utilises a crosslinked polyethylene (XLPE) insulation system.
Our XLPE insulation system is specially designed for HVDC transmission and has the electrical properties required to withstand high DC voltages. It is also cost-efficient, effectively manufactured in a cleanroom-classified environment that uses vertical extrusion line technology.
HVDC MI – mass impregnated cables
With excellent reliability and used since 1954 in power transmission projects at the highest DC voltage levels. Today's cables use copper conductors and are rated up to 525 kV. We provided the world´s first MI cable as well as the longest HVDC MI submarine cable system ever built.
