The invention relates to a high voltage swivel, comprising an annular outer element defining a cylindrical chamber around a longitudinal axis and an inner cylindrical element coaxial with the outer element and rotatable relative to said outer element around said longitudinal axis. The inner and outer elements each comprise at least two axially spaced electrical conductors which conductors are rotatable with the inner and outer elements, the conductors forming at least two pairs placed with contact surfaces in mutual electrical contact. One conductor in each pair is provided at the inner element, the other at the outer element and being connected to a respective voltage line which extends to an input terminal and to an output terminal respectively, the conductors being surrounded by an insulating material. The invention is characterised in that the electrical conductors of the outer element are provided in a recess in an annular solid outer insulating ring, the electrical conductors of the inner element are provided in a recess in an annular solid inner insulating ring, coaxial, with the outer ring, the inner and outer insulating rings each defining a boundary surface extending in an axial direction, the boundary surfaces of the rings being placed in close proximity, the electrical conductors being placed with their contact surfaces at or near the boundary surface.
