technical field

The utility model belongs to the technical field of power transmission equipment for electric energy transmission, in particular to a tubular busway structure.

Background technique

At present, most of the power transmission equipment with a voltage below 1kV uses cables or rectangular busbars for power transmission. The material cost of the cable is high, the quantity is large, the laying is complicated, and the service life is short; the rectangular busway is mainly composed of rectangular conductors, and the skin effect coefficient of a single rectangular conductor is small and the loss is low. For circuits below 2000A, multiple pieces of rectangular conductors are required to increase the ampacity. Due to the skin effect, the additional loss of the conductors also increases, and the more complex the busway structure, the higher the manufacturing cost.
