When should cable tray be used? Jinan Bridge is a good choice for the installation of a large number of cables in one area, such as the motor control room, the outer shelf room for DCS, the meeting control room, etc. Large cable tray can be separated from the motor control, enter the place of appearance and motor location, and further extend to the operation site to reduce the scale.

電纜橋架應裝置在物料溢出、化學品露出及設備損壞比較小的區域，假如遭遇物品溢出，很快就會被干紙漿、黑液和各種物體阻塞，造成火災危險。在工藝設備的維護過程中，焊接火花常常落到紙漿上，引發電纜橋架火災。在許多有電纜橋架的地方都發生過。

Cable tray should be installed in the area where materials overflow, chemicals exposed and equipment damage is relatively small. In case of material overflow, it will be blocked by dry pulp, black liquor and various objects, causing fire hazard. In the process of equipment maintenance, welding sparks often fall on the pulp, causing cable tray fire. It happened in many places where there are cable trays.

電纜橋架火災產生的煙霧分散要求在筆直或水平位置裝置防火板，根據組合電纜和電線的廠際防火，建議電纜橋架之間的比較小距離不該小于0.6m。在化學品濃度較高的區域，電纜橋架的裝置變得關重要。

For the smoke dispersion caused by cable tray fire, it is required to install fire prevention board in the straight or horizontal position. According to the inter factory fire prevention of combined cables and wires, it is recommended that the relatively small distance between cable trays should not be less than 0.6m. In the area of high chemical concentration, the installation of cable tray becomes very important.

任何不同金屬的觸摸都會導致電解，鋼支架與鋁電纜橋架直觸摸摸會導致電纜橋架和支架都被腐蝕。玻璃纖維不易受此影響，但會添加本錢。在此類惡劣環境中，運用玻璃纖維或許是除PVC穿線管之外的挑選。為幫助減輕火災損害和化學作用，加電纜橋架蓋板可以避免紙漿、石灰粉塵、礦物質進入。

The touch of any different metal will lead to electrolysis, and the direct touch of steel support and aluminum cable tray will lead to corrosion of cable tray and bracket. Glass fiber is not easily affected by this, but it will add cost. In such a harsh environment, the use of glass fiber may be in addition to PVC threading pipe outside the choice. In order to help reduce fire damage and chemical action, adding cable tray cover can avoid pulp, lime dust and minerals entering.

什么時候應該運用穿線管？當電力和操控線路的裝置環境惡劣、電纜數量較少、區域內充滿障礙物以及需求化學維護時，穿線管是正確的挑選。當需求電磁干擾屏蔽時，穿線管也是可以選擇。

When should a conduit be used? When the environment of power and control lines is harsh, the number of cables is small, the area is full of obstacles, and chemical maintenance is required, the conduit is the right choice. When EMI shielding is required, the threading tube can also be selected.

裝置穿線管的優點是可以維護電源和操控線路免受工業環境的損害。任何項意圖目標都是長期裝置規范，盡量削減穿線管的維護，運用多的規范穿線管類型為熱鍍鋅穿線管。在大型電纜裝置中，穿線管可以以更高的本錢到達相同的效果。

The advantage of the device is that it can protect the power supply and control circuit from the damage of industrial environment. The purpose of any project is to standardize the installation for a long time, reduce the maintenance of threading pipe as much as possible, and the type of threading pipe used in many specifications is hot-dip galvanized threading pipe. In large cable installation, the threading tube can achieve the same effect with higher cost.

關于沒有那么多電線的小型項目，穿線管是比較經濟的。穿線管具有堅持符合電氣規范的顯著優勢。一旦裝置結束，再移動填充的或許性很小。而電纜橋架是與電氣規范堅持一致的一個挑戰，開放式電纜橋架可以裝置更多電纜，但是誰來擔任監管?

For small projects without so many wires, the threading tube is more economical. The threading pipe has a significant advantage of adhering to the electrical specifications. Once the device is finished, the possibility of moving and filling is very small. The cable tray is a challenge to adhere to the electrical specifications. Open cable tray can install more cables, but who will be responsible for the supervision?

為了大限度地維護已裝置的電纜，穿線管是比較好的挑選。玻璃鋼電纜橋架也是耐化學腐蝕的理想挑選，但電纜露出在大氣或環境中，濟南橋架可以很好地支撐。

In order to maintain the installed cables to a large extent, the threading tube is a better choice. FRP cable tray is also an ideal choice for chemical corrosion resistance, but if the cable is exposed in the atmosphere or environment, Jinan cable tray can be well supported.
