Abstract
Electrical power distribution busway joints include opposing plates of conductive and non-conductive materials for connecting between adjoining busway sections. The non-conductive plates comprise glass-filled epoxy laminate sheets having high thermal conductivity, high electrical resistance and good mechanical strength in the presence of excess moisture.
Claims1
An electric busway joint having a pair of outer support plates and a plurality of electrically-conductive plates intermediate said support plates and a plurality of electrically-insulative plates intermediate said electrically-conductive plates, wherein each electrically-insulative plate comprises a plurality of planar layers arranged to form a laminate of about 75-160 planar layers per inch, each planar layer comprising a glass-filled epoxy composition having between about 35 to 75 weight percent glass, wherein the glass is arranged as a plurality of glass fibers embedded within said epoxy composition.
