First of all, we should understand the advantages and disadvantages of these two bus ducts, so as to accurately select the type according to their own use site and requirements.

空氣式插接母線槽散熱好、防潮性能好、輸送電流大、維護方便，母線槽可帶多個插孔，兩面出線，特別適用于對工廠設備供電。密集型母線槽是銅排經過絕緣處理后緊密的挨在一起，密封在外殼的里面，散熱通過外殼，效率也很高，其外形尺寸比空氣型的要小一些，而且不需要擔心會有異物落入槽內，影響正常工作，但密集型的會貴一些。

The air plug-in bus duct has good heat dissipation, good moisture-proof performance, large transmission current and convenient maintenance. The bus duct can be equipped with multiple jacks and outgoing lines on both sides, which is especially suitable for power supply to factory equipment. Dense bus duct is that copper bars are closely connected after insulation treatment and sealed in the shell. Heat dissipation passes through the shell, which is also very efficient. Its overall size is smaller than that of air type, and there is no need to worry that foreign matters will fall into the groove and affect normal work, but the price of dense bus duct will be more expensive.

在選擇母線槽時，如果預算充足亞威電纜的小編建議選擇密集型母線槽。但這種母線槽又分為很多的型號，這就需要根據具體的使用環境來選擇了。同是密集型的母線槽其導體材質分為銅排、鋁排和銅鋁復合三種，會有很大的差異。

When selecting bus duct, if the budget is sufficient, it is recommended to select dense bus duct for the small braid of Yawei cable. However, this bus duct is divided into many models, which needs to be selected according to the specific use environment. For the same dense bus duct, its conductor material is divided into copper bar, aluminum bar and copper aluminum composite, and the price will be very different.

絕緣性由于絕緣材料的不同也不一樣，還有外殼的材質及結構的不同也影響了散熱效果，不同的型號電容也不一樣，根據實際的需要選擇型號避免出現超負荷使用或電容過大投資浪費。

Insulation is also different due to different insulating materials, different shell materials and structures also affect the heat dissipation effect, and different models of capacitors are also different. Select models according to actual needs to avoid overload use or excessive investment waste of capacitors.

具體到使用環境其按照的方式不同也需要具體考慮，因為不同型號的母線槽其外形尺寸也不一樣，有的特殊的環境甚需要定制生產。

Specific to the use environment, it also needs to be considered in different ways, because the overall dimensions of different types of bus duct are also different, and some special environments even need customized production.
