Sumitomo Electric Contracts With 50Hertz To Replace Germany-Denmark Interconnector Land Cable On German Side

Sumitomo Electric Industries, Ltd., has been awarded a contract by German transmission system operator, 50Hertz, to replace part of the Germany-Denmark Interconnector (KONTEK).

The contract covers design, procurement, production, transport, civil work, and installation of XLPE*1 insulated HVDC cable and ancillary components. The contract also covers more than 10 years maintenance service, including emergency response to minimize the system unavailability.  

Sumitomo Electric has developed and commercialized unique HVDC XLPE insulation technology that withstands the Polarity reversal*2 operation required for conventional LCC Converter System.

Sumitomo Electric, which in 2019 successfully commissioned the NEMO Interconnector for Elia Group and UK National Grid, recently opened its Power Cable Project office in Germany to enhance the company’s capability to support customers in Europe throughout construction and maintenance phases.
