Innovative cable guidance from igus not only makes wind turbines more fail-safe

GENTING LANE, Singapore - Dec. 12, 2024 - PRLog -- The TRM triflex Rotation Module (TRM) by igus is a new cable guide designed to enhance the reliability and economic efficiency of wind turbines. It protects cables in flexible energy chains made of high-performance plastic during nacelle rotations up to 1,800°. This compact system, resulting from a design study, can be pre-fitted and customized for specific applications.

Wind turbines, especially offshore, require fail-safe systems due to their remote locations. The TRM ensures cables supplying power and data to the nacelle's generator, gearbox, and control systems are protected from heavy loads caused by constant nacelle movement. This reduces the risk of cable breaks and costly repairs. The pre-series version will be available from October 2024.

Rotary movements of up to 1,800°
The TRM system is located at the upper tower end of a wind turbine, just below the nacelle. It contains five triflex energy chains filled with energy and data cables, which can move in three dimensions. These chains form a ring-shaped structure, allowing rotational movement around a central axis. When the nacelle rotates, the TRM moves in sync with the energy chain, maintaining the bend radius and secure positioning of the cables. This controlled guidance allows for rotations up to 1,800° without tangling or kinking, enabling the nacelle to turn up to five times around its axis safely and efficiently.

Pre-fitting saves 50% assembly time
igus aimed to save space and installation time with the TRM. The compact module has an external diameter of 1,300mm and an installation height of less than 1m, requiring minimal space. Users can equip the system with cables on land or receive it fully harnessed from igus, which offers durable chainflex cables. This pre-fitted system can reduce on-site assembly time by up to 50%, according to Berteit.
