[0002] Cast-in-place bus duct is a system used for power transmission and distribution, usually made of copper or aluminum. Its main feature is that it forms a complete structure by embedding the conductor into the insulating material, thus providing good electrical performance and mechanical strength.

[0003] When pouring epoxy resin, the existing cast-type bus duct generally requires multiple people to assemble the casting mold, and when installing multiple conductive copper bars, multiple people need to cooperate with each other to neatly adjust and fix the conductive copper bars, thereby increasing the cost of labor input. At the same time, when pouring epoxy resin fluid, the top of the mold is generally open, and it needs to be poured manually step by step. After a period of time, the epoxy resin fluid at the initial position of the bottom of the mold will solidify and cannot blend with each other, thereby causing the epoxy resin fluid to be unable to fully fill the mold, resulting in some defects, affecting the integrity of the cast-type bus duct, and in the later stage of molding, it is generally left to stand and cool naturally, which increases the molding time of the bus duct. Therefore, the present invention proposes a rapid molding cast-type bus duct and a casting method thereof. Summary of the invention
