摘要：The present disclosure relates to an electrical insulation system (1) for a highvoltage electromagnetic induction device (18). The electrical insulation system (1)comprises a stick (3) having an elevated central portion (5) and two lateral portions (7, 9),which elevated central portion (5) is elevated relative to the two lateral portions (7, 9)and arranged between the two lateral portions (7, 9), wherein the elevated centralportion (5) defines a winding facing surface (5a) arranged to face a winding (19), whereinthe stick (3) has a barrier contact surface (13) opposite to the winding facing surface (5a),wherein a first distance between the winding facing surface (5a) and the barrier contactsurface (13) defines the thickness T of the stick (3), wherein the stick (3) has a first groove(11a), arranged between a first lateral portion (7) of the two lateral portions (7, 9) andthe elevated central portion (5), and a second groove (11b) arranged between a secondlateral portion (9) of the two lateral portions (7, 9) and the elevated central portion (5),which first groove (11a) and second groove (11b) extend axially along the stick (3),wherein each of the first lateral portion (7) and the second lateral portion (9) has a

respective groove adjacent surface (7a, 9a) opposite to the barrier contact surface (13),wherein a second distance ti from each groove adjacent surface (7a, 9a) to a plane (P1)defined by the winding facing surface (5a) fulfils the relation t1
