Abstract: The present invention relates to an insulated shaft joint (1) for electrically insulating a rotational member (2) from an end section of a shaft (3) to which the rotational member (2) is connected. The insulated shaft joint (1) comprises a plurality of first grooves (4) arranged in an outer surface of the end section of the shaft (3) and extending in an axial direction of the shaft (3), one or more rows of electrically insulating members (5), and an annular electrically insulating cage (6) arranged circumferentially around the plurality of first grooves (4). The insulating cage (6) comprises one or more rows of through-going openings (7), arranged circumferentially. The through-going openings (7) is being shaped and dimensioned so that they are adapted to surround and guide the insulating members (5). The rotational member (2) is arranged circumferentially around the annular electrically insulating cage (6).
