Background

The Bus duct is a new circuit type developed by the united states and called "Bus-Way-System" and is a new conductor formed by using copper or aluminum as a conductor, using a non-olefinic insulating support, and then being installed in a metal groove. The real practical application in japan was in showa 29 years (i.e., 1954), since which the bus duct was developed. Nowadays, the wiring system is indispensable for electrical equipment and power systems in high-rise buildings, factories, and the like. Because of the need of various building electric power of buildings, factories, etc., and the need has a tendency to increase year by year, the use of the original circuit wiring method, i.e., the pipe-through method, brings many difficulties in construction, and when the power distribution system is to be changed, it is almost impossible to make it simpler, however, if the bus duct is adopted, the purpose can be achieved very easily, and in addition, the building can be more beautiful. In terms of economy, the bus duct itself is expensive compared to cables, but the use of a bus duct makes construction costs much cheaper than those of a bus duct including various accessories for wiring and the entire power system, and this is particularly evident in the case of a large current capacity.

The bus duct is a closed metal device formed from copper and aluminium bus posts, and is used for distributing large power to every element of dispersion system, and in the indoor low-voltage electric power transmission main line engineering project, the bus duct can be used for replacing electric wire and cable, but the existent bus duct is poor in sealing property, and is easy to produce short circuit and fire hazard, and its structure is complex.
