HVDC Cable | Sumitomo Electric
Sumitomo Electric’s HVDC XLPE cable
enables polarity reversal operations and also significantly higher operational conductor temperature (90°C) to that of MI cables.
These features allow customers to achieve various benefits including reduced CAPEX,
increased operational margins, polarity reversal operations with conventional LCC converter or combination of cable and overhead line in the same system.
Our HVDC XLPE cable systems
provide solutions to satisfy the customer’s various requirements.
High Voltage DC(HVDC) Underground Cable Project for Amprion GmbH which sets new innovative benchmarks in the HVDC Industry.
Sumitomo Electric, with the support of its technology partner, Südkabel GmbH,
to deliver the world’s highest voltage 525kV XLPE Insulated HVDC underground cable system for the German TSO Amprion,
“Corridor A-Nord” project.
This project is considered one of the most critical power transmission infrastructure projects in the country
to support the “Energy Transition” of Germany to introduce more renewable energy to consumers and reduce the country’s CO2 emissions.
Sumitomo Electric will be responsible for

Sumitomo Electric Completes Long-Term Test for 525kV Cross-Linked Polyethylene Submarine Cable
– Wire & Cable India
Sumitomo Electric Industries, Ltd.
has completed the testing of its 525 kV cross-linked polyethylene (XLPE)-insulated high-voltage direct current (HVDC) submarine cable system
in accordance with the international standard CIGRE-TB496.
Also, a third-party certification body has approved the completion of the test.
With the increasing capacity of renewable energy sources and the necessity of long-distance power interconnectors between different countries and regions,
HVDC cable technology
has been gaining significant attention in the global market.
The technology
is suitable for long-distance power transmission.
Sumitomo Electric has recently completed a long-term test for its 525 kV DC XLPE submarine cable system, which can supply the industrial highest voltage for XLPE cables.
This system is capable of operating at 90°C and transmitting large capacities exceeding 2 GW,
thanks to the Company’s unique cable insulation technology using DC-XLPE compound and special fillers.
Also, its cable system has been qualified with flexible factory joint, offshore joint and transition joint to onshore cable,
which will enable us to propose a better solutions to projects which require long-distance and large-capacity power transmission.
In response to decarbonisation policies in various countries,
there has been a boom in the launch of renewable energy projects such as offshore wind power generation and the construction of interconnectors between countries and regions.
