JPS’s responsibility under the contract will be a full EPC including design, manufacturing and installation of a state-of-the-art HVDC XLPE insulated cable system - the first time it will have been used operationally as an HVDC system at DC 400 kV. XLPE is an abbreviation of cross-linked polyethylene. The needs for HVDC XLPE cable are increasing especially in Europe & North America where growing number of offshore wind farms and HVDC interconnection projects are under development. It has significant technical advantages, compared to conventional cable technology as outlined below.
Higher allowable operating temperature: It will allow NEMO LINK cable to have extra safety margin during cable operation, especially in cases where an unforeseeable situation creates excess current flows in the cable system or excess cable burial depth occurs due to sand wave mobility on the seabed, etc.
Environmentally friendly feature: XLPE cable does not require any oil as insulation material whereas conventional cable insulation does.
