Improved switchgear is disclosed that includes a bus bar system that can be assembled from modular parts. The bus bar system includes modules such as hi gh- voltage cables, connectors coupled to the cables and a third cable-less bus bar that is assembled using mechanical and/or push-on connections. By using these types of bus bars, various configurations, orientations of phase plane s, and sizes of bus bar systems may be assembled. The connectors and cable-less bus bar may include either push-on. connection points, mechanical connection s points or a combination of both. The bus bars may themselves include insulation and semiconductive shields. The improved switchgear may also include solid insulation, such as EPDM rubber, to insulate the bus bar syste m from the exterior surfaces of the switchgear.
