The utility model discloses optimize bus duct casing on prior art's basis to numerous beneficial effect have been brought:

1. through the bus duct shell of integrative casting shaping's last casing and lower casing grafting mode installation, save time and workman's intensity of labour greatly when the installation, and two casing grafting modes make the whole seam significantly reduced of shell, and the waterproof nature of "U" type rubber slab messenger grafting seam department of adding on this basis improves greatly to improve the holistic waterproof nature of casing, have apparent progress.

2. On the basis of the beneficial effects, the installation site avoids the processes of more traditional site parts and complex operation, so that the installation site is neat and orderly, and the development direction of green construction is met.

The concave radiating ribs are compared with the traditional convex single linear radiating ribs or radiating ribs with other shapes, on the basis that the surface area of the outer surface of the shell is increased, the surface area of the inner side environment is also increased, and the surface area of the radiating ribs with other shapes in the prior art, which is contacted with the inner environment, is not changed, so that the concave radiating ribs greatly improve the radiating effect compared with radiating ribs with other shapes; it should be noted that, in order to achieve an ideal sealing effect when the sealing device is used in a dense bus duct, a sealing component with good heat conduction can be added in the heat dissipation ribs.
