Abstract
A bus coupling for connection to bus in an electrical system including a coupling having a substantially cylindrical outer surface and an inner surface for receiving the bus. A portion of the outer surface of the coupling and the bus are compressed by a swaging tool until they plastically deform radially inwardly to form a swaged connection. An anti-oxidant composition may be applied between the coupling and the bus, with an annular groove in the inner surface of the coupling accumulating any of the excess composition. A counterbore on the inner surface at one end of the coupling may be filled with a sealing material to prevent water accumulation that could weaken the connection in freezing climates. The one end of the coupling also has a smooth, curved surface to reduce the adverse consequences normally associated with the corona effect.
