Sumitomo to replace 400 kV Kontek onshore cable
Electric Industries has been awarded a contract to replace the onshore
part of the Kontek
on the German side. The contract includes design, procurement, production,
transport, civil work, and installation of XLPE HVDC cable and ancillary
components. The turnkey contract also includes 10 years of maintenance
service, including emergency response, to minimize system unavailability.
Managing Executive Officer of Sumitomo Electric, Yasuyuki Shibata, said:
‘Sumitomo Electric’s XLPE cable is the perfect solution for the requirement
of KONTEK to retrofit aged fluid-filled cable systems to more reliable
and environmentally friendly technology. Considering the fact that a number
of cable systems in the world with old technologies need to be replaced
in coming years, we are confident that our XLPE solution will become a
benchmark in the industry.’
The 170 km Kontek
is an HVDC connection between Germany and Denmark. The 600 MW Kontek
connection has been in service since 1995 and reached its operational age
now. The German TSO, 50Hertz, started the subsoil investigation of the
14 km land route in December 2019. The land cable will run between the
landing site in Markgrafenheide and the transformer station in Bentwisch.
The new route of the cable will be laid parallel to the existing route
during ongoing operations. The existing route will be rebuilt once the
new route is operational.
The planning application for the new land cable was submitted to the Ministry
of Energy, Infrastructure and Digitalization in Mecklenburg-Western Pomerania
in November 2020. The 50 km long submarine part of the link
was replaced in 2010, after a series of faults in the previous cable.
