The Development History Of Bus Duct

The busway is a new circuit method developed in the United States called "Bus-Way-System". It uses copper or aluminum as a conductor, is supported by non-olefinic insulation, and is then installed in a metal groove. conductor. The real practical application in Japan was in Showa 29 (ie 1954), and the busway has been developed since then. Nowadays, it has become an indispensable wiring method in electrical equipment and power systems such as high-rise buildings and factories. Due to the demand for electricity in various buildings such as buildings and factories, and this demand tends to increase year by year, the use of the original circuit wiring method, that is, the pipe-through method, brings many difficulties during construction, and when the power distribution system needs to be changed. , it is almost impossible to make it simpler, however, if the busway is used, it is very easy to achieve the purpose, and it can also make the building more beautiful. Economically speaking, the bus duct itself is more expensive than the cable, but the use of the bus duct can make the construction cost much cheaper compared with various accessories including wiring and the entire power system (as shown in Figure 1). ), especially in the case of large current capacity, this situation is more obvious.
