1、金属线槽垂直或倾斜安装时,应采取措施防止电线或电缆在线槽内移动。山东电缆桥架

1, metal trough vertical or inclined installation time, measures should be taken to prevent the wire or cable groove moving online.

2、金属线槽布线搬适用于正常环境的室内干燥和不易受机械损伤的场所明敷,但对金属线槽有严重腐蚀的场所不应采用。

2, metal trough wiring move is suitable for the normal environment of indoor dry and not easy to place Ming fu by mechanical damage, but have serious corrosion on metal trough should not be used.

3、由金属线槽引出的线路,可采用金属管,硬质塑料管、半硬塑料管、金属软管或电缆等布线方式。电线或电缆在引出部分不得遭受损伤。

3, line arise out of the metal trough, can use metal, hard plastic tube, half-hard plastic pipe, metal hose, or cable wiring. Wire or cable shall not damage in parts.

4、同一回路的所有相线和中性线,应敷设在同一金属线槽内。同一路径无防干扰要求的线路,可敷设于同一金属线槽内,线槽内电线或电缆的总截面(包括外护层)不应超过线槽内截面的20%,载流导线不宜超过30根。

4, all of the same loop phase line and neutral line, should be equipped in the same metal trough. The same path without the requirement of interference lines, can be equipped on the same metal trough, trough the total wire or cable cross section (including outer sheath) should not exceed 20% of the line groove section, current-carrying wire should not be more than 30 roots.

控制、信号或与其相类似的线路,电线或电缆的总截向下应超过线槽内截面的50%,电线或电缆根数下限。

Control, signal, or similar lines, and its total wire or cable should be cut down by more than 50% of the line groove section, the number of wire or cable.
