Before the 1980s,the main problem in the design of power supply backbone systems for senior management and buildings could be addressed by using a common network cable from an enterprise.The cable was laid along the wall in an electrical shaft using brackets or cable trays.

　　As a power supply backbone,cable companies are much safer and more reliable than bare wires and bare cables.However,the management of current carrying capacity is limited,and the cable cross-section cannot be made very large(the maximum problem can only be 400mm²).Moreover,the cable is too thick,making on-site construction technology difficult.In the mid to late 1980s,the continuous development of urban socio economy led to the rapid development of Chinese culture,with a large number of high-rise and super high-rise construction enterprises building.The electricity load of buildings increased sharply,and the limitations of cables as our own power supply backbone became increasingly important.Especially in China,the difficulty of designing and producing cable branch joints on site has a great impact on the management of technical personnel,and there is an urgent need to establish a high-capacity and convenient branch power supply backbone to replace it.

　　At this time,the CESKO bus duct with large capacity and convenient tapping was introduced from abroad,and its rapid economic development in data processing system engineering can effectively promote the research and application of information technology in the market.If bus ducts are used,it is very easy to achieve teaching objectives,and it can also make the building more beautiful.

　　Bus way system is a new type of circuit and educational material called"Bus Way System"designed by the United States for analyzing,researching and developing environmental issues related to enterprise development.It uses copper or aluminum as a conductor for students to become themselves,supported by non vinyl insulation technology personnel,and then sensors are installed in different metal slots to form a new type of teaching activity material conductor.The real need for Japanese companies to solve practical applications in daily life was in 1954,and since then,bus ducts have been developed in China's social and economic development.Nowadays,in high-rise buildings,factories and other electrical control engineering construction equipment,power resource management information systems have become an inevitable wiring method due to their lack.

　　Due to the electricity needs of various construction enterprises such as buildings and factories,and the increasing trend of students'development through learning this technology year by year,the use of their original circuit wiring design work method,namely the conduit method,has brought many economic difficulties to our lives during construction.Moreover,when it comes to changing the distribution management information system,it is almost impossible to simplify it.However,if teachers can use bus ducts,it is very easy to achieve the purpose of educational activities,and it can also make the building more beautiful.

　　From the perspective of economic and social development capacity,our country needs to analyze and compare bus ducts with cables,which are more expensive.However,compared with various accessories including wiring and the entire Chinese power resource management information system,using bus ducts can make the construction cost of an enterprise much cheaper,especially in the case of large current capacity.This way of learning and living is even more obvious.

The busbar trunking system is a more efficient distribution device for transmitting current in enterprises, especially suitable for the needs of social and economic organizational structure design and rational wiring in increasingly tall buildings and large-scale factories. The high-level management ability of modern Chinese traditional corporate culture companies, as well as the work, study, and life of buildings and large workshops, require us as a problem with huge electrical energy. Faced with this huge load, which requires hundreds or thousands of amperes of strong current, we need to choose safety education research to provide reliable conduction equipment. The research and design method of busbar system is a good choice for students.

Bus ducts, as power supply main lines, have strong development advantages compared to ordinary cables. International standards stipulate that the service life of power system cables is 8-15 years. Therefore, it is increasingly being replaced in the study of urban life in large and medium-sized cities in China; The service life of busbar trunking can reach 50 years. It has become a new type of transmission technology equipment and is the preferred product for current and future construction projects.
