A breaking device for interrupting current includes an electrically conducting outer member, an electrically conducting inner member arranged radially inside the outer member with respect to a breaking axis and an electrically insulating or semiconducting breaking member arranged radially between the outer member and the inner member with respect to the breaking axis, where the breaking member is arranged to move along the breaking axis from a starting position to a protruding position in which the breaking member protrudes from a space within the outer member for interrupting a current between the outer member and the inner member and the breaking member includes a first tubular including a first insulating material and a second insulating material, where the first insulating material has a higher wear resistance than the second insulating material.

A method for producing an electrical power device having an insulator. The method includes, by means of additive manufacturing, applying a polymeric insulating material forming part of the device. The method also includes, in a subsequent consolidation step, subjecting the insulator to elevated temperature and pressure during a predetermined time period to consolidate the insulator.
