525 kV extruded HVDC cable system

The world´s first 525 kV extruded HVDC cable system doubles power transmission over longer distances with the same low losses

The ground-breaking 525 kV extruded HVDC cable system has a power rating of up to 2600 MW, and is ideal for delivering larger amounts of electrical power over longer distances than was previously possible. The cable system is designed for submarine as well as underground applications, and utilizes a new DC cross-linked polyethylene (XLPE) insulation material, a uniquely developed material technology; oil and porcelain-free terminations based on ABB bushing technology, as well as cable joints for efficient installations.

Why ABB?
ABB’s 525 kV extruded HVDC cable system is a key element in the vision of a DC grid that utilizes renewable energy generation more efficiently. The cable system meets international standards and recommendations for extruded cable systems, including the extensive qualification-by-type and long-term pre-qualification tests. ABB has once again launched record-breaking innovation, thus taking power transmission systems to the next level.

 

  • Complete cable system verified through extensive testing
  • Specially designed accessories that utilize proven technologies and innovative solutions, which together enhance capacity
  • The 525 kV extruded HVDC cable system offers a 64% increase in voltage, which enables capacity of up to 2,6 GW
