HIGH VOLTAGE INSULATOR AND COOLING ELEMENT PROVIDED WITH THE HIGH VOLTAGE INSULATOR

PROBLEM TO BE SOLVED: To provide a high voltage insulator having a low leaking speed. SOLUTION: The high voltage insulator H comprises a coaxial arrangement, an insulation tube 1 having end edge portions in a shape of a bearing ring 10, a hollow metal armature 2 supported by the bearing ring 10, an adhesive joint 51, and a cavity 15. At least one channel 50 for adhesive agent which is mainly guided in a diameter direction is arranged between the cavity 15 and the adhesive joint 51, and the channel 50 of the adhesive agent is sealed by a hardened adhesive agent and moreover has a cross section sufficient for guiding an unhardened adhesive agent from the cavity 15 into the adhesive joint 51 before formation of a hardened adhesive layer.
