    电缆桥架结构类型的选择您现在所在的位置: 首页 > 电缆桥架结构类型的选择

  在设计文件中通常笼统地称呼“桥架”,并未指出具体的结构特征。结构类型的混乱会带来工作现场散热、机械防护方面的问题。电缆桥架(cablesupportingsystem)常用的有以下几类:

  a.电缆托盘(cabletray),具体又分为有孔托盘、无孔托盘和组装式托盘三种,具体定义可以参考中国工程建设标准化协会标准<CECS31:2006钢制电缆桥架工程设计规范》,散热性能和机械?;ば跃又械?,电缆桥架托盘特别适合于现场灵活组装。

  b.电缆梯架(1adder—typecabletray,stair—tvpecabletray),通风散热性能好,机械?;ば圆?。

  C.槽式电缆桥架(cabletrunking,channel—typecabletray),散热性能差,但机械?;ば院?,能有效地防护外部有害液体和粉尘的侵入。电磁屏蔽效果也佳。
