Since November 2025, authorities in Australia have been investigating findings of asbestos in the brake pads of wind turbines. The affected components include service lifts, material hoists, and braking systems within the turbines. The investigations were triggered by positive test results on imported components originating from the supply chain of the Chinese supplier 3S Industry. The primary focus is on Goldwind installations, as well as Vestas turbines located at the Golden Plains Wind Farm. Consequently, specific areas of the facilities have been cordoned off while operators conduct further inspections of systems supplied by 3S, Avanti, and Hailo.
Discovery of Asbestos Affects Safety-Critical Braking Systems
The case does not involve rotor blades or tower structures. Nevertheless, it does not concern a harmless minor component; brake pads generate fine particulate abrasion during use and wear.
therein lies the precise risk. Asbestos becomes particularly critical when fibers are released through abrasion. In wind turbines, an additional factor comes into play: the contaminated components are situated high above the ground. If fibers escape at such heights, the wind can potentially carry them over considerable distances. For this reason, braking systems in these turbines are considered particularly sensitive components.
Australia Confirmed; Extent of Reach Remains Unclear
To date, reliable evidence has emerged primarily from Australia. There, the issue affects several states. Goldwind and Vestas are at the center of the controversy, as multiple positive test results have been made public.
A global scandal has not yet been proven. Nevertheless, it would be premature to give the all-clear. The affected lift and hoisting systems originate from international supply chains.
The Problem Extends Beyond Wind Power
No manufacturer can fully inspect every supplied component. This applies to wind turbines just as it does to trains, cranes, elevators, or industrial plants. A rigorous risk classification system is therefore crucial.
Components subject to heat, friction, and abrasion require stricter controls. Paper documentation alone is insufficient in such cases. Spot checks must be targeted precisely at those points where prohibited substances pose the greatest danger.
The Industry Must Adopt More Targeted Inspections
The response was belated, but decisive. Operators isolated the affected areas. Furthermore, replacement programs and additional material tests are currently underway.
For local residents, authorities currently classify the risk as low. For maintenance teams, however, direct contact with wearing brake components remains a critical concern.
