Bessakerfjellet Wind farm

Project description:

• The Bessakerfjellet wind farm comprises the areas of Mehøgda, Storhøgda and Blåfjellet in Roan municipality in the county of Sør-Trøndelag.
• The installation consists of 25 wind turbines, each with an output of 2.3 MW. Average annual production is estimated at 176 GWh.

Customer’s challenges:

• The customer required a complete solution with specially adapted unspliced TSLF-O 24 kV cable lengths, from the secondary station to the turbines and between the turbines.
• The distance between the turbines is approximately 200 to 300 metres.
• A potential need for fibre to be blown in at a later date.

Nexans’ solutions:

• In order to reduce costs, each length and drum were uniquely marked to ensure simple and efficient progress in the project.
• The wind farm is managed remotely from TrønderEnergi’s control centre via fibre cables that were blown into the TSLF-O cables, the three power phases having been twisted along with three empty tubes in the spaces between the twists to allow the future blowing of fibre cables.
