槽式橋架是一種全封閉型電纜橋架，它適用于敷規劃算機電纜、通訊電纜、熱電偶電纜及其它高活絡體系的操控電纜等。下面山東電纜橋架廠家來講講槽式橋架布線安裝六個注意要點。

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、一般金屬線槽布線適用于正常環境的室內枯燥和不易受機械損害的場所明敷，但對金屬線槽有嚴峻腐蝕的場所不該選用。

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、金屬線槽應牢靠接地或接零，但不該作為設備的接地導體。

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

3、同一回路的一切相線和中性線，應敷設在同一金屬線槽內。同一途徑無防攪擾要求的線路，固線器，可敷設于同一金屬線槽內，線槽內電線或電纜的總截面（包含外護層）不該超越線槽內截面的20％，載流導線不宜超越30根。操控、信號或與其相類似的線路，電線或電纜的總截向下應超越線槽內截面的50％，電線或電纜根數下限。

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、橋架(電纜匯線橋架)筆直或歪斜裝置時，應采納辦法避免電線或電纜在線槽內移動。

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、由金屬線槽引出的線路，可選用金屬管，硬質塑料管、半硬塑料管、金屬軟管或電纜等布線方法。電線或電纜在引出部分不得遭受損害。

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、線糟應平坦、無歪曲變形，內壁應潤滑、無毛刺。

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

槽式電纜橋架產品能夠有用的促進工程環進和耐久性的要求，具有重量輕、成本低、裝置便利、散熱透氣性好等長處。它一般適用于直徑較大電纜的敷設、非常適用于高低壓動力電纜的敷設。您對此有需求就來我們網站http://www.ymmgjx.net關注聯系吧！

The trough type cable tray products can effectively promote the requirements of the engineering ring and durability, and have the advantages of light weight, low cost, convenient installation, good heat dissipation and ventilation. It is generally applicable to the laying of large diameter cables, especially for the laying of high and low voltage power cables.
