空气式母线槽设计采用了单螺栓夹紧端子，为母线槽单元连接元件，可以减少安装时误操作，同时只要栓紧一个螺栓，就能将两个母线槽单元连接起来，捶孔母线槽在捶孔处设计保护挡板，只有当防护挡板拉开时插孔平时不用时可将防护板拉开并封锁死，减少了在插区处灰尘和异物的进入，从而增加母线槽的防护性能，母线槽设计了四个电流等级，三个级次的外壳相邻，变换容量时，母线不换外壳，大大方便了安装，传输电能大。适用于展览馆、宾馆、银行、娱乐等场所电力馈电及配电使用，具有安装方便、体积小、容量大、设计施工周期短等特点。
The design of KMXC series of air type bus duct uses the advanced single bolt clamping terminaI as the con—nected components for bus duct unit，which can avoid mis-operation when installing．Two bus duct units can be connected rapidly and reliably as long as blotting a bolt tightly．The hole bus duct with s higher protection degree is eauipped with protective board．Only when the protective board is open，jack box can be inserted. If the jack hole needn't be used，the protective board can be opened and add lead to lock the hole．In that case，dust and foreign matedal would be prevented from the insert area and improve the protection performance of the bus duct. The bus duct has four current ratings and three enclosure adjacent grades．When changing capacity，the covering doesn't need to be replaced，this makes installation greatly conveniently and can transfer high energy. It can be appIied to the exhibition．hotel，banks，entertainment places for power feeders and distribution，with the features of safety in operation，convenient maintenance，small volume，big capacity，short construction periods and long working life.
