A busway system, by application, typically consists of a starting busway, straight-through busway (available in both with and without sockets), L-shaped vertical (horizontal) bends, Z-shaped vertical (horizontal) offsets, T-shaped vertical (horizontal) tees, X-shaped vertical (horizontal) quads, variable capacity busway, expansion busway, relevant accessories, and fastening devices for busway.
Busbars can be categorized into three types according to the insulation method: air-insulated busbar, dense-insulated busbar, and high-strength busbar.
High-strength enclosed busway (CFW). Its manufacturing process is not restricted by sheet material, with the casing designed in a tile groove shape to enhance the mechanical strength of the busbars. The horizontal sections of the busbars can be produced up to 13 meters long. The intentional separation and fixation of the busbars at the groove positions, with a spacing of 18mm between them, ensures good ventilation between the wires, significantly improving the moisture-proof and heat dissipation functions of the busway, making it particularly suitable for southern climates. The presence of gaps between the wires reduces the temperature rise of the conductors, thus increasing overload capacity and reducing magnetic oscillation noise. However, it generates much higher stray currents and inductive reactance compared to dense busways, so when compared with the same specifications, its conductive busbar cross-sectional area is larger than that of dense insulated busbar connectors.
