Abstract:
1. High voltage swivel ( 1 ), comprising an annular outer element ( 2 ) defining a cylindrical chamber around a longitudinal axis ( 27 ) and an inner cylindrical element ( 3 ) coaxial with the outer element ( 2 ) and rotatable relative to said outer element around said longitudinal axis ( 27 ), the inner and outer elements each comprising at least two axially spaced electrical conductors ( 15 , 16 , 17 , 18 ; 28 , 29 , 30 , 31 ) which conductors are rotatable with the inner and outer elements ( 2 , 3 ), the conductors forming at least two pairs ( 15 , 28 ; 16 , 29 ; 17 , 30 ; 18 , 31 ) placed with contact surfaces in mutual electrical contact, one conductor in each pair ( 15 , 16 , 17 , 18 ) being provided at the inner element ( 3 ), the other ( 28 , 29 , 30 , 31 ) at the outer element ( 2 ) and being connected to a respective voltage line ( 32 , 33 )) which extends to an input terminal ( 6 ) and to an output terminal ( 7 ) respectively, the conductors ( 15 – 18 , 28 – 31 ) being surrounded by an insulating material, characterised in that, the electrical conductors ( the electrical conductors (
