Abstract: A swivel device for a wind cone tower assembly comprises a rotating housing, provided with channels for drainage of condensation from its interior, and a fixed axle on which this housing is mounted. Two split bushings of insulated material are offset placed on each other between the surface of the fixed axle and a pair of slip rings. Brushes with enhanced content of copper are used and an insulating coating is applied around the brush holders to prevent electrical leakage. A conductor bushing also of insulating material for protecting the electrical conductors extending perpendicularly from the interior of the fixed axle to the pair of slip rings mounted on this axle.
