Regional environment it is complex, influence factor in need of consideration also compare it is more；Since the design phase more will not be after cable
Phase maintenance is taken into account, and leads to when equipment repair that there are do not see, touched not at part cable connection, especially key node
, the problems such as reaching, and than more prominent, therefore the maintainability in cable later period just becomes the content that wiring needs primary study.
When carrying out wire cable layout, for the maintainability for improving cable, it is necessary to ensure that the installation of cable associated components can make to examine

Space and the cable weight for reducing cable designs expense, saving equipment compartment as far as possible.Since the selection of cable is in layout designs
When it has been determined that improve cable performance should shorten its length as far as possible, reduce its deformation, in addition the reduction of design cost
It is mainly determined by length of cable, cable weight is also mainly influenced by length at this time.If therefore most short with cable trails, change
