Developing a 66 kV Infrastructure

The transition to 66 kV cables, transformers and switchgears has long been touted as a necessary step for the wind industry. In the space of a few short years progression has been very quick as the industry attempts to streamline every aspect of wind farm construction and energy production to realise reductions in the levelised cost of energy.

Read this article and get an insight into the following aspects:

  • JDR Cables 66 kV Inter-Array Cables
  • Commercial Applications
  • Prysmian Group Manufacturing 66 kV Submarine Cable Cores
  • ABB WindSTAR Transformer
  • Siemens Transformer and Switchgear

The technological move: Advantages of 66 kV cables

At the Hannover fair in 2015 the cable manufacturer Nexans presented a 630 mm² copper cable. Most visitors probably simply walked past the short lenght of cable. They thus missed a small revolution in offshore wind power technology, as the cable had passed all the relevant tests for tpye approval. 

Where are we today in 2017?
Read the article to get more knowledge on the acceleration of development:

  • Cost savings
  • Acceleration of development
  • Good temperature behaviour

"The market is currently still right at the start of implementing this technological move!"

Questionnaire

Expert interview with Nexans - the 66 kV cabling technology

Stefaan Mensaert, Product Line Manager Renewables at Nexans gave us the opportunity to talk to him about 66 kV cables, junction boxes and connectors. As an experienced cable manufacturer, he gave us some answers to the following topics:

  • Major challenges to overcome in order to deliver 66 kV XLPE insulated submarine cable and the accessories, junction boxes and connectors
  • What kind of tests they executed to ensure quality and high performance of 66 kV cabling technology
  • Nexans and the Blyth project in the UK
  • Future for offshore wind energy 66 kV inter-array cabling
