A high voltage swivel, includes 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 thereto around the axis. The inner and outer elements each include at least two axially spaced conductors 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 conductors of the outer element are provided in a recess in an annular solid outer insulating ring, the conductors of the inner element are provided in a recess in an annular solid inner insulating ring.
