Nexans pushes new low-voltage toroidal aluminum cables for wind turbines
With Nexans' new solution for low-voltage toroidal aluminum cables and accessories, energy transmission inside wind turbines will become more cost-effective
.
The elastic cable system can be used for connections up to 1 kV and is able to withstand torsional forces
caused by the rotation of the nacelle depending on the wind direction.
By producing lighter and more resilient cables, this initiative highlights the cost-effectiveness of wind energy and moves the renewable energy sector towards a more reliable supply of green energy worldwide
.
The WINDLINK® solution developed by Nexans includes toroidal aluminum cables, connectors and connecting tabs for wind turbine generators, which are lighter
than conventional copper cables.
This type of cable is ring-shaped in the engine nacelle, allowing it to withstand the torsional forces
generated by the nacelle moving in the direction of the wind.
After that, the cable will transmit power down from the engine room to the fixed area of the tower and then to the transformer
.
This new resilient toroidal aluminum cable solution complements the existing rigid aluminum
cables.
The lower density of aluminum means that the cable is 40% lighter than conventional copper cable, making it easier to install
inside wind turbines.
The system is designed for a life cycle that will match the life
of the wind turbine.
The new toroidal aluminum cable and its special accessories have undergone a 3-year development period, including rigorous laboratory tests
.
Nexans faced challenges
in developing more cost-effective, lighter and more resilient aluminum cables and accessories that could withstand the torsional forces generated by nacelle movement.
Nexans tests a variety of aluminum alloys to find solutions
for optimal performance.
According to torsion tests, the selected aluminum cable can withstand ± 100 degrees/meter of torsion in at least 2,000 cycles, while providing the same performance
as conventional copper cables.
Nexans has also developed connectors and tabs that have been tested
for aging in third-party laboratories.
Philippe Michel, Global Product Manager for Nexans Wind Power Equipment, said: "Nexans plans to reduce the cost of low-voltage ring cables while ensuring the required performance
for wind turbines.
Our new low-voltage toroidal aluminium cable is the first in the market to meet these standards
.
”
The complete cable concept will be manufactured
by Nexans at its plant in Bonn, France, and Hove in Germany.
