Joint assembly for a busduct

A busduct assembly comprising first and second busduct sections, each busduct section comprising a plurality of busbars located within a busduct housing wherein said busbars extending beyond said housing at either end thereof, and a joint assembly comprising a stack of electrically insulating separator plates arranged in mutually adjacent pairs, each pair of separator plates having at least one electrically conductive connector plate located therebetween, each pair of separator plates defining a respective busbar receiving gap therebetween for receiving respective busbar ends of adjacent busduct sections to be in contact with the at least one connector plate therebetween such that said connector plate provides electrical continuity between respective busbars, upper and lower cover plates being located on either side of the stack of separator plates, the separator plates and connector plates having mutually aligned apertures formed therein, a fastener extending between said cover plates and through said mutually aligned apertures in order to clamp the separator plates and connector plates between the cover plates, a side cover being provided on at least one side of the stack of separator plates extending perpendicular to the separator plates, said side cover having at least one heat exchange rib extending from an inner face of the side cover to extend into the stack of separator plates, wherein said at least one heat exchange rib extends between adjacent pairs of separator plates, on an opposite side of the separator plates from the associated busbar receiving gap, wherein respective busbars of the first busduct are electrically coupled to corresponding busbars of the second busduct via the joint assembly.
