Patent ID: 8403679

Claim:
A high voltage swivel, comprising: an inner body; and an outer body, the inner and outer bodies being coaxial around a longitudinal axis and being rotatable relative to one another around the longitudinal axis, wherein each of the inner body and the outer body has at least a first and a second ring-shaped conductor element, the first and second conductor elements comprising two spaced-apart end faces and a curved contact surface, the first and second conductor elements being mutually interconnected at opposing end faces via insulating members at axially spaced-apart positions, each conductor element of the inner body and the outer body being connected to a voltage line extending to an input terminal or an output terminal, the curved contact surface of each inner conductor element is adjacent to and in electrical contact with an opposed contact surface of a corresponding outer conductor element, the insulator members interconnecting the conductor elements are situated at a mutual distance in the circumferential direction of the conductor element, and the interconnected conductor elements of the inner and the outer body form an open cage-like construction, each interconnected conductor element being supported by a respective support member to form integral units that are adapted to be mutually decoupled or attached by relative displacement of the integral units in the direction of the longitudinal axis.
