Wind turbine connecting solutions

Wind turbine, renewable power generation The wind turbine captures the wind’s energy and converts it into electrical power. It comprises a nacelle and a tower. The nacelle houses both the rotor hub and the DC generator. Each of these parts integrates both low and medium voltage control systems, also high voltage components at the base of the tower. All of these components are within a confined area and subjected to a high level of stress. 1 2
