电缆桥架通常用于敷设电缆且其外形像一座桥，是统称。由主体（托盘或梯架）、附件、支/吊架等部件构成，用于支承电缆线路且具有一定刚度的结构系统电缆梯架：侧板+横档（若干），一定刚度的梯形部件。电缆梯架横档间有很大的空隙，敷设电缆时应防止电缆从横档的空隙中下垂，因此梯架水平敷设时通常只能敷设大截面电缆电缆托盘：底板+侧板，用于直接承托电缆荷重的刚性槽形部件。电缆槽盒是一种全封闭的电缆桥架，也常称电缆线槽槽盒对控制电缆屏蔽干扰和一般腐蚀环境中电缆的防护都有较好效果，且较为美观散热性：电缆梯架(全敞开式)＞有孔托盘＞无孔托盘＞槽盒

　　Cable trays are commonly used for laying cables and have a bridge like appearance, which is a general term. A structural system cable ladder consisting of a main body (tray or ladder), accessories, supports/hangers, etc., used to support cable lines and has a certain degree of rigidity. Cable ladder: side panels+crossbars (several), trapezoidal components with a certain degree of rigidity. There is a large gap between the crossbars of the cable ladder, and when laying cables, it is necessary to prevent the cables from sagging from the gap in the crossbars. Therefore, when laying the ladder horizontally, only large section cable trays can be laid: bottom plate+side plate, which are rigid groove shaped components used to directly support the cable load. Cable tray is a fully enclosed cable tray, also known as cable tray. It has good effects on shielding interference of control cables and protecting cables in general corrosive environments. It is also aesthetically pleasing and has good heat dissipation: cable ladder (fully open)>perforated tray>non perforated tray>tray
