A busway and a method of assembling the same in which a flowable, uncured epoxy is applied between insulated busbar conductors that are stacked on top of one another and inner surfaces of the busway housing into which the stacked conductors are placed to form an enclosed busway. The busbar conductors are insulated by an epoxy powder coat, which can develop pinholes during the curing of the epoxy powder. A flowable, curable dielectric material, such as epoxy, is applied between the outermost busbar conductors and the inner surfaces of the top and bottom pieces of the busway housing. Optionally, epoxy is also applied between adjacent pairs of busbar conductors, which are stacked and arranged into the housing. Pressure is applied to the housing stack, and the epoxy is allowed to cure, resulting in a busway having superior thermal performance, dielectric integrity, and mechanical strength compared to conventional busways.

Method of busway construction

A busway joint pack includes a first connector plate and a second connector plate that is spaced from the first connector plate such that the connector plates are configured to engage a pair of phase-conductors of a pair of busway sections. The busway joint pack further includes a first insulator assembly and a second insulator assembly. Each of the insulator assemblies includes a heat sink and two electrically insulating sheets on either major side surface of the heat sinks. The insulator assemblies are positioned adjacent to the connector plates such that the insulating sheets electrically insulate the heat sinks from the connector plates. Side panels are positioned adjacent to the heat sinks and abut end surfaces thereof to aid in transferring heat generated in the busway joint pack to the surrounding environment via the heat sinks and side panels.
