The utility model relates to the field of transformer station equipment, and specifically relates to a tubular bus T-joint fitting capable of satisfying engineering practical demands. A novel integrated tubular bus T-connection fitting comprises an upper T-shaped wire clamp (1), a lower T-shaped wire clamp (2), a buckle (3) and a connecting piece (4), and is characterized in that one end of the connecting piece (4) is vertically connected with the upper T-shaped wire clamp (1), the other end is vertically connected with the lower T-shaped wire clamp (2), and the upper T-shaped wire clamp (1) is vertical; and the wire clamps on the upper T-shaped wire clamp (1) and the lower T-shaped wire clamp (2) are connected through a buckle (3). The number of used tubular busbar connection fittings isreduced, connection points are reduced, and heating positions are reduced. Under the condition that the electrical distance requirement is met, the distance between tubular buses arranged in a crossedmode is reduced, the work amount is reduced, waste is avoided, and the operation difficulty is lowered.
