b' is inserted so that the ends of both the upper and lower flanges 14 of the side plate 2' are in contact with the fixing angles 10, respectively, and the upper flanges 14 of the side plate 2' are each in contact with the ceiling plate of the waterproof cover main body 11. let Next, the inner flange 1 of the opening of the waterproof cover main body 11
The bottom plate 12 is fluid-tightly fixed to the waterproof cover main body 11 by abutting the bottom plate 12 between the holes 5 and 5 through the packing 16, and screwing nuts 18 onto the bolts 17 passing through these. In this case, care must be taken so that both flanges 14 below the side plate 2' abut against the bottom plate 12 when the bus duct is assembled.

れずに設置することができる。 In a tightly insulated bus duct with such a configuration,
By inserting the pre-assembled bus duct body into the waterproof cover, a tightly insulated bus duct can be formed, making assembly of the tightly insulated bus duct easy. The bus duct body is firmly fixed with the fixing angle of the waterproof cover and the bottom plate.
The mechanical strength against short circuit currents can be significantly increased. Furthermore, both the upper and lower flanges of the side plates that make up the bus duct body are in direct contact with the ceiling and bottom plates of the waterproof cover, respectively, and there are ventilation rows in the upper and lower parts of these side plates, resulting in good heat dissipation characteristics. Compared to the tightly insulated bus duct shown in the figure, since no insulating spacer is used, damage to internal parts due to twisting can be prevented. Furthermore, since the number of assembly parts is small, it can be assembled compactly and is lightweight, and furthermore, the insulating bag duct can be easily transported and installed, and is economically advantageous. In addition, since the waterproof cover is composed of a U-shaped cover body and a bottom plate that closes the opening, it is possible to further improve the waterproof performance of the closely insulated bus duct. It can be installed without being restricted by the installation location.
