1.空气型的母排和外壳结构简单，特别是插接孔较多的情况下，因而价格便宜。空气型母排的固定方式是采用绝缘衬垫来支撑，根据动稳定的要求设置相应的跨度尺寸和线间距离。所以它动稳定性能不及密集型母线槽。

Bus 1 air type and the shell has the advantages of simple structure, especially the inserting hole is larger, so cheap. Fixed way air type busbar is the use of insulating pad to support, distance set corresponding span size and line according to the requirements of the dynamic stability of the inter. So its dynamic stability can't intensive bus groove.

2.由于母线间和母线与外壳间均存在着空气介质，这对母排的散热性能大为减少，因而降低了它的载流量。

because the bus and bus and the shell. There are air medium, the heat dissipation performance of bus is greatly reduced, thus reducing the traffic load of it.

3.国产的空气型母线槽均将裸铜排配置了散热缩套，这固然对加强绝缘和散热均有好处.但同时也增加了造价。空气型母线槽的外壳结构简单，对多插孔的母线较为有利。

Air type bus slot 3 domestic will bare copper heat shrinkage sleeve configuration, this is to strengthen the insulation and heat dissipation benefit but also increases the cost. The shell structure of air bus bar groove is simple, more favourable busbar of multiple jacks.

4.空气型母线槽采用宽厚比大的母线，受到动稳定的限制，所以多为宽厚比小的母排，这样它的发热量大而散热量小。限制了它的载流量。所以它用于小电流母排合适。用于大电流时，它的性价比将大大下降。

The 4 air type bus slot adopts the width thickness ratio of bus, by dynamic stability limit, so more generous than small bus, so heating value it's big and small heat. By limiting the traffic load of it. So it is suitable for small current bus. For high current, its price will be greatly reduced.

5.空气型母线槽母排的连接结构简单，制造工艺容易，安装方便。空气型母线槽母排的感抗大，其电压损失大，适用于小电流近距离的线路。

The 5 air type busbar busbar connection has the advantages of simple structure, easy manufacturing technique, convenient installation. Air type busbar busbar inductance, the voltage loss, suitable for small current close line.
