ABSTRACT:
An insulating support means mounts a bus conductor on a grounded metal wall through which the bus conductor extends. The bus conductor has a thin coating of insulating material bonded to its exterior. The support means comprises a porcelain sleeve mounted on the metal wall and surrounding the bus conductor, with the inner periphery of the sleeve disposed in spaced relationship to the insulating coating. Positioned between the inner periphery of the porcelain sleeve and the insulating coating is a disc of resilient insulating material closely surrounding the bus conductor. This disc has an axial length much shorter than the porcelain sleeve and is thus spaced axially from both ends of the porcelain sleeve.
