Before the 1990s, cables played an important role in the low-voltage distribution system. But since the 1990s, the busbar slot system has been gradually introduced and developed, and has quickly been widely used in construction engineering. Compared with traditional transmission equipment, it has its unique performance advantages, such as large carrying capacity, strong overload capacity, convenient separation, good heat dissipation and convenient maintenance.   The bus trough power supply system is usually the main line from the distribution center to scattered flexible power supply, while the cable power supply is limited by factors such as difficult separation, small load capacity, and difficult dispersion control. It is usually "point to point" power supply, especially in the power supply system of high-rise buildings, the superiority of the bus trough is particularly prominent compared with the cable. Traditional cable power supply mode, each floor needs to set out separately, the number of cables. Such a intensive laying method, poor heat dissipation, large space, difficult accident inspection, difficult maintenance. As long as the single central bus slot power supply system is used, and the corresponding capacity plug box is set in each floor for distribution, the power supply purpose can be achieved. This way makes the split extremely flexible, and each branch has the plug box to protect the shunt transformer. Therefore, using the bus groove is safer, simpler and more reliable. The bus bar saves space, while the cable needs a lot of space. The bus groove can be controlled in the position nearest to the equipment, while the cable must be controlled in the distribution room. The bus is provided with standard mounting supports without additional support; cables must be laid with separate bridges or piping. The bus groove can last up to 50 years and is reusable. The cable is short and can not be reused. The branch interface of the bus groove can increase the tap loop, and the cable must be laid in the distribution room. The insurance cost of installing the bus is lower, while the cable is relatively high.

The voltage drop index of the general low-voltage system transmission lines mainly depends on the resistance, capacitance reactance and inductance reactance of the transmission lines. The air-type enclosure is made of magnetic material (steel), and the eddy current phenomenon is obvious, with large capacitance reactance and inductance reactance, obvious voltage drop and large power loss. However, the compact structure of the compact busbar greatly reduces the impedance of the busbar system. The aluminum-magnesium alloy enclosure further avoids the occurrence of magnetic hysteresis and eddy current phenomenon, resulting in a very small voltage drop of the entire system and very low energy consumption. It generates less heat and dissipates heat quickly. The compact busbar has an extremely low impedance feature that is unmatched by the air type busbar, and the heat generation index of the compact busbar is smaller. The busbar system is a fully enclosed structure, and the maximum protection level can reach IP68. Therefore, the heat transfer method of the compact busbar is "thermal conduction", which can quickly dissipate heat through the copper busbar and the aluminum-magnesium alloy enclosure, greatly enhancing the conductive efficiency of the copper bar and optimizing the current-carrying section of the copper bar. The heat transfer method of the air type busbar is "radiation", and the thermal "conduction" between metals is bound to be superior to the thermal "radiation" of the gas medium. Moreover, the majority of the shells of air type busbar channels adopt steel enclosures, resulting in poor heat dissipation effect. In order to ensure the current-carrying capacity of the busbar channel, it is necessary to increase the section of the copper bar, increasing the cost. Therefore, relatively speaking, the cost performance of the air type busbar channel is not high and it is gradually eliminated and updated by the market. The air type busbar has an inevitable "chimney effect". Once there is a fire at one point, its hollow structure acts exactly like a chimney, accelerating the spread of the fire, presenting a serious safety hazard. The air type busbar has less strict requirements on the environment and can meet the needs of spaces with relatively high humidity, high-rise buildings, etc. It has a very obvious advantage in terms of product durability. The air type busbar is convenient for maintenance. The air type adopts the method of insulation spacer plus bolt fixation, and in an emergency, the insulation components and conductors can be disassembled and replaced on site. The insulation of the air type busbar channel is in the form of insulation spacers plus bolt fixation, so the insulation effect also has a great advantage over the compact busbar channel.

Project Overview In order to ensure the safe power supply of the terminal building, Guangzhou Baiyun International Airport adopts voltage temporary drop comprehensive management for sensitive electrical equipment. The original joint venture brand Busway needs to be dismantled and customized current specification products need to be added for integration and use. Seeking help from the original joint venture brand Busway manufacturer was unsuccessful, stating that they were unable to provide corresponding products and supporting service solutions.   Project requirements The on-site safety supervision unit requires the contractor to cooperate in implementing the "three musts and four requirements" to ensure the safety of the construction site, otherwise they cannot enter the site for construction; Three musts: all stages must wear masks throughout, all items entering must undergo security checks, and all personnel entering must pass safety exams and apply for approval; 4 requirements: requiring continuous electrical construction work, requiring safety supervisors to be present for construction work, requiring construction to be carried out according to airport regulations, and requiring each construction unit to ensure timely completion of the project; Solution We utilized the PHS model to tailor products and service implementation plans for the airport, effectively meeting project requirements and completing them on schedule. Through the "trade in" service, recycles existing products, greatly reducing the cost of project renovation.   Project results The project came to a perfect conclusion through the joint efforts of multiple parties, among which Ohory made effective project planning for various difficulties, ensuring the smooth progress of the project, and ultimately received recognition and praise from the airport side.
