槽式桥架是一种全封闭型电缆桥架，它适用于敷规划算机电缆、通讯电缆、热电偶电缆及其它高活络体系的操控电缆等。下面 山东电缆桥架厂家来讲讲槽式桥架布线安装六个注意要点。

The trough type cable tray is a fully enclosed cable tray, which is suitable for laying computer cables, communication cables, thermocouple cables and other control cables of high flexible systems. Next, Shandong cable tray manufacturers will talk about six points for attention in the installation of trough type cable tray wiring.

1、一般金属线槽布线适用于正常环境的室内枯燥和不易受机械损害的场所明敷，但对金属线槽有严峻腐蚀的场所不该选用。

1. General metal trunking wiring is suitable for exposed laying in dry indoor places and places not easily damaged by machinery in normal environment, but it should not be used in places with severe corrosion to metal trunking.

2、金属线槽应牢靠接地或接零，但不该作为设备的接地导体。

2. Metal trunking shall be firmly grounded or connected to neutral, but shall not be used as the grounding conductor of equipment.

3、同一回路的一切相线和中性线，应敷设在同一金属线槽内。同一途径无防搅扰要求的线路，固线器，可敷设于同一金属线槽内，线槽内电线或电缆的总截面（包含外护层）不该超越线槽内截面的20％，载流导线不宜超越30根。操控、信号或与其相类似的线路，电线或电缆的总截向下应超越线槽内截面的50％，电线或电缆根数下限。

3. All phase wires and neutral wires of the same circuit shall be laid in the same metal trunking. For the lines without anti disturbance requirements in the same way, the wire fixer can be laid in the same metal trunking. The total cross section (including the outer sheath) of the wires or cables in the trunking shall not exceed 20% of the cross section in the trunking, and the number of current carrying wires shall not exceed 30. For control, signal or similar lines, the total section of wires or cables shall exceed 50% of the section in the trunking and the lower limit of the number of wires or cables.

4、桥架(电缆汇线桥架)笔直或歪斜装置时，应采纳办法避免电线或电缆在线槽内移动。

4. When the bridge (cable tray) is straight or skewed, measures shall be taken to avoid the movement of wires or cables in the trunking.

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

5. Wiring methods such as metal pipe, hard plastic pipe, semi-hard plastic pipe, metal hose or cable can be selected for the lines led out from the metal trunking. Wires or cables shall not be damaged at the outgoing part.

6、线糟应平坦、无歪曲变形，内壁应润滑、无毛刺。

6. The wire slot shall be flat without distortion and deformation, and the inner wall shall be lubricated without burr.
