Abstract: Thus provided is a wind turbine. The wind turbine has a nacelle with a first end and a second end, at least one air inlet and one nacelle housing with a nacelle interior. A first heat source in the form of an electric generator is provided, wherein the generator generates electrical energy and a first heat loss. A second heat source in the form of at least one electrical device is provided for converting the electrical energy generated by the generator in the nacelle interior, wherein the electrical devices generate a second heat loss, and are arranged in the nacelle housing. A cooling system with a liquid cooling system and an air cooling system for the first and second heat source is provided. An air treatment unit is provided in the nacelle interior, which has a droplet separator and a recirculating chiller. The droplet separator is designed to free the air flowing in through the air inlet of liquid droplets.

Abstract: A form-wound coil of a stator of a generator of a gearless wind power installation is provided. The form-wound coil includes an electrical conductor with a first and a second terminal. The terminals are used serve in each case for electrical connection to a further form-wound coil. The terminals in each case have a thread for electrical connection using a screw. A winding structure, a stator having the form-wound coil, and a method for producing the stator are also provided.

Abstract: A method for forming a tubular body, comprising the following steps: making available a tubular body having a first and a second tube end, filling the tubular body with a liquid, closing the tubular body, and forming the tubular body.
