More about the Middelgrunden Project (Denmark):
In December 1999 nkt cables was awarded the contract of linking the world’s largest offshore wind farm with the existing electricity grid. The order included 12 km three core 36 kV XLPE submarine cable, transformers and switchgear. The installation was completed in 2001. It consists of two submarine cables from the main connection of the farm to Amager Power Station and a 5 km long cable for the interconnection of 20 windturbines (cluster cables). Fibre optic cable is integrated in the submarine cable to secure communication and control of the turbines.

Medium Voltage and High Voltage Submarine Cable Systems for Wind Farm Projects Continuously in Business for more than 130 Years
What began with submarine telecom cables more than 130 years ago was continued with paper insulated power cables and subsequently with the development of Power Cable Systems, based on XLPE technology up to the highest current levels. Therefore, nkt cables builds on this experience when it comes to tailormade and economic power transmission installations for onshore and offshore applications.
