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.

A swivel device for a windcone tower assembly comprises, in combination
- a rotating housing provided with means for drainage of condensation from its interior to its exterior, said means for drainage being located in a wall of a lower cavity of said rotating housing;
- attaching means extending from said rotating housing and adapted to connect a windcone;
- a fixed axle on which said rotating housing is supported, at its extremities, through two spaced bearings;
- means for providing electrical insulation between a pair of slip rings and said fixed axle;
- brush means attached in the interior of said rotating housing and located substantially in a zone between said bearings;
- means for preventing electrical leakage from or to said brush means;
- and
- means for protecting electrical conductors extending from the interior of said fixed axle to said pair of slip rings.
