Abstract
A bushing structure for switchgear includes first and second separate support structures each having surfaces defining at least one opening. The support structures are coupled together so that the openings define a passage through the bushing structure and so that a slot is defined between the first and second support structures, surrounding the passage. A bushing is disposed in the passage and has a body, a bus receiving member, and a compression structure. The bus receiving member has an opening there-through sized to receive a bus bar. When the first and second support structures are coupled together with the bushing in the passage, the compression structure is disposed in the slot, sandwiched between the first and second support structures so that they exert pressure on the compression structure.
