裝甲型匯流排的“三明治”結構相對空氣型匯流排“柵格式”結構明顯存在體積小、佔用空間小的優勢；The "sandwich" structure of the compact busbar has obvious advantages of small volume and less space occupation compared with the "grid-like" structure of the air type busbar.
一般低壓系統輸電線路的電壓降指標主要取決於輸電線路的電阻、容抗、感抗，空氣型外殼為磁性材料（鋼），渦流現象明顯，具有較大的容抗和感抗，電壓降明顯，電能損耗較大；而裝甲型匯流排緊密的結構，大大降低了匯流排系統的阻抗，鋁鎂合金外殼更加避免了磁滯渦流現象的產生，使得整個系統電壓降非常小，能耗非常低；發熱量小、散熱快；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.
裝甲型匯流排擁有空氣型匯流排難以比擬的低阻抗特點，在發熱指標上裝甲型匯流排更小；匯流排系統是全封閉結構，防護等級最高可達到IP68,所以裝甲型匯流排熱傳遞方式為“熱傳導”，能很快通過銅母排和鋁鎂合金外殼把熱量散發，大大提升銅排的導電效能，優化了銅排的載流截面；空氣型匯流排傳遞方式為“輻射”，而金屬間的熱“傳導”勢必優越於氣體介質的熱“輻射”，而且空氣型匯流排外殼大多數採用鋼制外殼故而散熱效果不佳，為了保證匯流排的載流需要必須加大銅排截面，增加了成本，所以相對而言空氣型匯流排的性價比不高，漸漸被市場淘汰更新。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.空氣型匯流排外殼組裝基本採用螺栓連接，裝甲型匯流排採用全自動鉚接系統組裝，前者在電氣運行（伴隨震動）過程中極容易發生螺栓鬆動、脫落，存在安全隱患，而後者摒棄了傳統的螺栓連接，電氣連續性好，同時避免了人為因素，裝配精度高。The assembly of the enclosure of the air type busbar is basically by bolt connection, while the compact busbar is assembled by a fully automatic riveting system. In the former case, during the electrical operation (accompanied by vibration), bolt loosening and shedding are extremely likely to occur, posing a potential safety hazard. In contrast, the latter discards the traditional bolt connection, has good electrical continuity, and avoids human factors at the same time, with high assembly accuracy.
空氣型匯流排有著它難以避免的“煙囪效應”，一旦一處著火，其中空式的結構正好充當煙囪的角色，使得整個火勢蔓延速度加快，存在嚴重的安全隱患。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.
1、空氣型匯流排對環境的要求不太苛刻，能滿足相對濕度較大的空間、高層建築等等，在產品的耐用性上有非常明顯的優勢；1. 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.
2、空氣型匯流排維護方便，空氣型的採用絕緣隔塊加螺栓固定的方式，緊急情況可以在現場拆開更換絕緣件和導體。2. 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.
3、空氣型匯流排絕緣是使用絕緣隔塊加螺栓固定的方式，所以絕緣效果也比裝甲型匯流排有很大的優勢。3. 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.
