Master efficiency at high power levels
Our high voltage direct current (HVDC) offshore cable systems enable efficient long-distance transmission at high power levels, interconnecting regions and countries and electrified oil and gas platforms. This technology also allows a secure and stabilising connection to existing electricity grids.
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.
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.
Reduction of 620,000 tons of CO2 emissions per year with a climate-efficient oil and gas production. Watch and learn more about the world’s longest extruded power connection from shore to the Johan Sverdrup, one of the five largest oil fields outside Norway
