对于无特殊要求的建筑物配线,从美观和安全等角度考虑,一般采用暗管敷设方式。但导线暗管敷设不仅要消耗较多的钢管和接线盒,而且施工和维修也极不方便。为了找出一种较合理的导线敷设方式,我们在本厂一座两层的仪表修理楼电气设计中,采用了墙槽内导线暗敷设的配线方式,竣工使 For the wiring of buildings without special requirements, from the perspective of aesthetics and safety, dark pipe laying is generally adopted. However, the laying of conductor conduits not only consumes more steel pipes and junction boxes, but also is inconvenient for construction and maintenance. In order to find out a more reasonable wire laying method, in the electrical design of a two-story instrument repair building of the factory, we used the dark wiring of the wiring in the wall slot.
