While wind energy is one of the cleanest, greenest and safest ways to generate energy, the turbines that are required for the process face some harsh environments. From high humidity in India to very high altitudes in the mountains of South China, wind turbines - or windmills - have been installed in almost every place imaginable, across the world. Often, you’ll find them in remote, deserted places sometimes only reachable by helicopter, which can make maintenance exceptionally difficult. This means that repair works on systems and components inside these wind turbines needs to be kept to a minimum. Clearly, the quality of these applied components is paramount.
