ABSTRACT:
An elongated section of bus duct having U-shaped insulating pieces surrounding the longitudinally extending edges of the stacked bus bars and a flat insulating sheet of a material which does not adhere to the U-shaped insulating pieces disposed between the bus bars. The flat insulating sheets can also be disposed between the housing and the outside stacked bus bars which are compressed by the housing. The non self-adhering U-shaped pieces and the flat insulating sheets permit the insulated bus bars to slide with respect to each other due to differentials in expansion and contraction of the bus bars. The sliding action, of the U-shaped insulating pieces and the flat insulating sheet, prevents rupture of the primary insulation layer which is applied to the bus bars and which is self-adhering at operating temperatures and pressures.
