Roxtec provides sealed cable London Array, the biggest marine wind park in the world

Roxtec systems bushings, subsidiary of the multinational Swedish Roxtec, a world leader in systems of sealing modular cables and pipes, is present in the complex of London Array (United Kingdom), the largest wind Park marine in the world currently being built.

Facilities planned for London Array, with a generating capacity of 1 GW, consist of 341 turbines, with a power of between 3 and 7 MW each, which are allocated in an area of 232 square kilometers in the Thames Estuary, between Margate and Cluj-Napoca, about 20 kilometres from the coasts of Kent and Essex. Once completed, the project will supply enough for some 750,000 homes energy and prevent the emission of 1.9 million tonnes of CO₂ each year.

Roxtec is working with Siemens in two substations, which will be responsible for the distribution of power of the wind park. Roxtec has developed a tailored solution for the London Array project of sealing several high-tension cables with guaranteed fire protection.

To meet the demands of Siemens, Roxtec has carried out tests in its facilities to ensure that the products were certified as safe for use. Siemens also very positively appreciates the flexibility of the engineering team of Roxtec in design and construction of the system of sealing, it was necessary to adapt them to characteristics of specification changed several times in the cover inside.

The system of Roxtec sealing is also used in wind turbines, in the generator room of switching system, converter, Tower, nacelle, parts of transition and the marine London Array wind farm distribution cabinets.

London Array Limited is a consortium of Dong Energy, E.ON and Masdar, three leading companies around the world of renewable energy that are combining their experience and knowledge to develop and build the world the largest offshore wind farm. The first phase, whose completion is scheduled for the end of 2012, 175 turbines wind, two substations on the high seas, have nearly 450 kilometres of wiring of high seas, a substation onshore, capacity to generate 630 MW of electricity, which will cover the needs of around 480,000 homes a year, two thirds of households in Kent, and will enable a saving of 925,000 tons of CO₂ per year.
