Electrical Infrastructure Facilities

Advancing product performance, efficiency and speed to market for complex offshore electrical, materials, mechanical and environmental systems.

Test Services

As offshore wind develops into deeper, harsher environments, lifetime product performance of critical electrical infrastructure is vital to maintaining cost-effective levels of power efficiency to the grid. We specialise in providing extensive test programmes across a wide variety of complex electrical transmission and distribution infrastructure, operated from UKAS-accredited laboratories.

We work with clients on component development, materials selection, system certification, electrical grid integration and accelerated lifetime test programme delivery, improving reliability and ensuring complex multiple arrays and generation sources operate at optimum efficiency.

  • Type certification of HV cable systems, switchgear and other HV insulation systems
  • HV insulation breakdown testing up to 600kV AC, 1MV DC
  • Product development, testing and certification support
  • HV bushing and transformer performance testing
  • Accelerated ageing testing
  • Polymeric materials testing
  • Environmental assessment and testing
  • Temperature and process data telemetry
  • Fault finding, failure investigation and diagnostics
  • Static and fatigue mechanical testing.

Test Facilities

UKAS-Accredited HV And Materials Laboratories

Accredited facilities for the testing of power cable systems, capable of providing type testing services for underground and submarine cable systems.

Levenmouth Demonstration Turbine

A live 7MW offshore wind turbine, enabling analysis and furthering understanding of electrical infrastructure as part of overall turbine performance.


Dynamic Cable Test Rig

A bespoke, state-of-the-art cable bend fatigue test rig supporting the development – and improving the performance and reliability of – subsea cables. The rig is capable of testing floating wind and tidal cables, carrying out operational research, and acting as a representative test bed for all aspects of subsea cable development. Unique features include:

  • Testing up to three samples simultaneously.
  • Testing while fully submerged in seawater.
  • Performing electrical and mechanical testing simultaneously.
  • Testing within a UKAS-accredited laboratory.

ORE Catapult’s considerable expertise in materials analysis and HV testing has been a crucial factor in bringing 66kV technology to the market and will help ensure that offshore wind technology continues to develop in the drive to reduce lifetime costs.

Value-Add Services

UCAS-Accredited Testing

Our HV electrical laboratories are the UK’s only accredited facilities for the testing of power cable systems, capable of providing type testing services for underground and submarine cable systems.

Bespoke Design And Management Of Test Programmes

We provide clients with new and bespoke test programmes, as well as guidance on test processes and requirements. We can design bespoke tests to support client requirements to better understand and optimise their products.

Materials Analysis And Validation

We can provide an extensive service in materials analysis and validation. Clients are able to undertake analysis as part of the HV electrical testing programmes, immediately after testing, without causing delay or damage to test samples.
