Thermally efficient ventilated electric busway system
摘要:
An electric busway system consists of a plurality of planar bus bars insulated from each other and bolted together for good mechanical strength and for efficient thermal conductivity. The bus bars are additionally perforated to promote convective air current flow through the perforations when the bus bars are mounted in the horizontal plane.
