A bushing structure for a switchgear includes a mounting portion constructed and arranged to mount the bushing structure. A barrel portion extends from the mounting portion and is coaxial there-with. The barrel portion includes a plurality of undulations in a peripheral surface thereof to increase creepage distance. A primary contact is disposed within and extends a length of the barrel portion. The primary contact has a first end constructed and arranged to be contacted by a movable contact of the switchgear and a second end constructed and arranged to be connected with a busbar.
