Jinan cable bridge is already a very common equipment in our life. Of course, there are still many problems that we do not understand. We need to find more resources and make better use of it. So does the cable in Ji 'nan cable bridge need to be pierced?
Cable tray as a supporting project of wiring engineering, there is no special specification guidance, the specification form of each manufacturer is lack of versatility, therefore, the design and selection process should be based on the type and quantity of electrical cables of each system, reasonable selection of suitable bridge.
Does the cable in Ji 'nan cable bridge need to be pierced? It is necessary to wear a slightly larger steel tube or flexible tube according to the cable size when you wear the bridge.
Function of cable threading: avoid or reduce the probability of interference on the way; Avoid the interference of electrical and cable around the line on the way; Other circumstances requiring pipe penetration. For example, if the output cable of a high-power converter interferes with other signal cables in the cable tray, it can not be solved by other ways, and there is no other route, it may be forced to wear the pipe.
According to the building layout, combined with air conditioning pipeline and electrical pipeline Settings, convenient maintenance, as well as the density of cable routing to determine the best route of cable bridge. In the room, as far as possible along the walls of the building, column, beam and floor erection, such as the need to use the comprehensive pipe gallery erection, should be set up in parallel on the side or above the pipeline, and consider the lead line and branch line as far as possible to avoid crossing, if there is no other pipe frame borrowed, it is necessary to set up (support) column.
In the engineering design, the layout of the bridge should be based on the comprehensive comparison of economic rationality, technical feasibility, operation safety and other factors to determine the scheme, but also fully meet the requirements of construction, installation, maintenance and cable laying. When the bridge is laid horizontally, the height from the ground is generally not less than 2.5m. When the bridge is laid vertically, the part below 1.8m from the ground should be protected by metal cover plates, except when laid in the electrical special room. If the cable tray is horizontally laid in the equipment interlayer or the horse path and lower than 2.5m, protective grounding measures should be taken.
Does the cable in Ji 'nan cable bridge need to be pierced? In fact, this depends on the site situation and the purpose of laying cables, and cannot be generalized. Come to our website for more information!
