Background

The Bus duct is a new circuit mode developed by the United states and called as a 'Bus-Way-System', and is a novel conductor formed by taking copper or aluminum as a conductor, using 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 of 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 lower 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 uses copper or aluminum as a conductor, uses non-olefinic insulation support, and then is mounted on a metal shell to form a novel conductor, the conductor material mainly uses copper and is heavily conductive, the metal shell is important protection for isolating the conductor from the outside, the material of the metal shell determines the service life of the bus duct to a great extent, and the metal shell of the existing air type bus duct still has the problems of low toughness, low strength and low hardness.
