The cable system also features a high allowable operating temperature, which allows Nemo Link 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. With this milestone in the cable industry, Sumitomo Electric underlined its technology leadership in the market. Once the interconnector goes into full commercial operation in the first quarter of 2019, Nemo Link will become the highest voltage HVDC XLPE cable system in the world at 400 kV which is currently limited to 320 kV. Sumitomo Electric and JPS's responsibility under the contract is a full Engineering, Procurement, Construction and Installation (EPCI) including design, manufacturing, installation and commissioning of the state-of-the-art HVDC XLPE insulated cable system. Land cable (left) and submarine cable (right) This new interconnection increases security of power supply for both countries, allowing the import and export of electricity, as well as supporting the integration of renewable energy in the grid. Nemo Link connects the two countries' power grids over a total length of 141.5 km with a combination of 130 km HVDC submarine and 11.5 km land cables manufactured and installed by Sumitomo Electric and JPS. J-Power Systems Corporation (JPS), a subsidiary of Sumitomo Electric, signed a contract in 2015 for design, manufacturing and construction of HVDC interconnector cable system between UK and Belgium with Nemo Link Limited, a joint venture between Elia (Belgian TSO) and National Grid (UK), to exchange electricity up to 1,000 MW between the UK and Belgium. This system, which is scheduled to be in commercial operation in the first quarter of 2019, will transmit the world's highest voltage of 400 kV with crosslinked polyethylene (XLPE)* 1 insulated DC cable. An inauguration ceremony was held at the Belgium substation site on December 5, 2018. is pleased to announce that it has completed the connection of a high-voltage direct current (HVDC) interconnector cable system between the United Kingdom and Belgium after the high voltage test.
