Wind turbines have emerged as an alternative energy source in many countries all over the world. Wind farms can be built in any location that has a stable wind flow, meaning both on-shore and off-shore. Modern wind turbines can be controlled and managed remotely. Due to the power generation and possible EMC risk, there is a preference to use fiber optics for the data transmission inside of the tower.
As the nacelle follows the direction of the wind, the cables inside of the tower are frequently twisted. And that must be ensured within a wide range of temperatures.
