High Voltage Cable Systems

Martin Henriksen, HVDC cable systems programme director.

To allow the wide-scale integration of renewable energies, networks must be able to transmit electricity over long distances and for this, HVDC cable systems are essential. We support the development of innovative solutions to ensure the reliability of underground and subsea HVDC cable systems.”

Martin Henriksen, Department Director – High Voltage Cable Systems

We provide a wide range of services and solutions for HVDC grids, MVDC grids and offshore wind farm grid connections.

Thanks to our understanding of insulating materials behaviour under high dielectric and thermal stresses, we drive the development of high-performance materials for HVDC cables and accessories.

As reliability is a key concern for the transmission system, we develop innovative methods and devices for HV cable monitoring based on analyses of the physical phenomena that cause ageing in insulation materials.

We design and operate various test platforms to reproduce the life conditions of high voltage cable systems and subsea equipment: standard type testing conditions, new types HVDC systems transients, combined high voltage and hyperbaric conditions.

Monitoring and diagnostics of HVDC cable systems.
Precise modelling of HVDC cables, taking into account the physical phenomena of direct current.

Our projects cover:

  • New composite insulating materials for DC cable system components.

  • Monitoring, physical modelling and diagnostics of DC cable systems.

  • Dielectric testing of DC cable systems.

  • High Voltage subsea cable systems for offshore wind farm grid connections.
