濟南電纜橋架是電氣工程中用于支撐和保護電纜的重要設備，選擇合適的電纜橋架對于保障電氣系統的和穩定關重要。然而，很多人在選擇電纜橋架時常常感到困惑，不知道該如何下手。究其原因，主要是因為對濟南電纜橋架的關鍵因素了解不夠深入。那么電纜橋架型號結構是什么？又應該如何選型呢？

Jinan cable tray is an important equipment used in electrical engineering to support and protect cables. Choosing a suitable cable tray is crucial for ensuring the safety and stability of the electrical system. However, many people often feel confused when choosing cable trays and do not know how to proceed. The main reason is that the understanding of the key factors of Jinan cable tray is not deep enough. So what is the model and structure of the cable tray? How should we choose?

常規橋架型號有槽式無孔托盤、有孔托盤、梯架、中間加隔板的、還有網格式，

The conventional cable tray models include slotted non perforated trays, perforated trays, ladder frames, those with intermediate partitions, and mesh formats,

1、槽式橋架

1. Trough bridge

槽式無孔托盤橋架，室內外電纜線敷設如果不需要考慮散熱，用槽式無孔托盤橋架就對了，因為它密封性好，可以抵擋一切外部因素對槽體內電纜線的損壞，從而更好的達到防護作用。

If heat dissipation is not required for indoor and outdoor cable laying, using a slot type non perforated tray bridge is the right choice because it has good sealing and can withstand all external factors that may damage the cables inside the slot, thus achieving better protection.

2、托盤橋架

2. Tray bridge

有孔托盤橋架，它跟無孔托盤橋架其實結構形狀是一樣的，唯獨它槽體底部多了散熱孔，因為口徑大的電纜線正常運行時，會有很大的熱流，就需要具備散熱性的橋架敷設，如果要有很好的密封性防護又要散熱效果的，選有孔托盤橋架。

A perforated tray bridge has the same structural shape as a non perforated tray bridge, except that it has heat dissipation holes at the bottom of the groove. When large-diameter cables run normally, there will be a lot of heat flow, so a tray with heat dissipation is needed for installation. If you want good sealing protection and heat dissipation effect, choose a perforated tray bridge.

3、梯式橋架

3. Ladder style bridge

梯架，我們也叫它梯式橋架，它優勢也是散熱透氣性好，而且它的載荷力比無孔托盤和有孔托盤更強，它常被用于直徑較大的電纜敷設，特別是高低壓動力電纜，電纜功率大了，梯架可以起到更好的散熱性和載荷力。

Ladder frame, also known as ladder bridge, has the greatest advantage of good heat dissipation and air permeability. Its load capacity is stronger than that of non perforated trays and perforated trays. It is often used for laying larger diameter cables, especially high and low voltage power cables. With higher cable power, the ladder frame can provide better heat dissipation and load capacity.

4、中間加隔板的橋架

4. Bridge with partition in the middle

中間加隔板的橋架，現在你們看到的這個是無孔托盤中間加了塊隔板的橋架，這塊隔板一樣可以加在，有孔托盤、梯架還有網格式橋架里面，當動力電纜和控制電纜敷設在同一條橋架內，這塊隔板就可以把它們很好的分開，防止電磁干擾，來確保控制電纜正常運行。

The bridge with a partition added in the middle, what you see now is a bridge with a non perforated tray and a partition added in the middle. This partition can also be added to perforated trays, ladder frames, and grid trays. When power cables and control cables are laid in the same bridge, this partition can separate them well to prevent electromagnetic interference and ensure the normal operation of control cables.

5、網格式橋架

5. Network format bridge

網格式橋架，網狀形狀，這類橋架做網絡通訊工程的朋友肯定不陌生，常用于網絡數據機房里面，數據網絡機房電纜線多，口徑功率大，且頻繁需要引入/引出的布線，網格橋架就起到它的優勢了，散熱性好且方便維護。

Network format cable trays, with a mesh like shape, are definitely familiar to friends who are engaged in network communication engineering. They are most commonly used in network data rooms, where there are many cables, large power diameters, and frequent wiring needs to be introduced/introduced. Grid cable trays have their advantages, with good heat dissipation and easy maintenance.

在選擇電纜橋架時，需要考慮以下幾個關鍵因素：

When selecting cable trays, the following key factors need to be considered:

1、電纜類型和數量：根據電纜的類型和數量，選擇合適的橋架形式和種類。例如，如果電纜需要做屏蔽抗干擾，應選用帶隔板的潮濕橋架；如果電纜只需要一般的保護或在正常溫度且干燥的環境中，選擇潮濕橋架即可。

1. Cable type and quantity: Choose the appropriate cable tray form and type based on the type and quantity of cables. For example, if the cable needs to be shielded and anti-interference, a damp cable tray with partitions should be selected; If the cable only requires general protection or in a normal temperature and dry environment, a damp cable tray can be selected.

2、環境因素：在強腐蝕環境下，應選擇熱氣型橋架和鋁合金橋架。同時，還需要考慮戶外安裝時可能遇到的風載、雪載等因素。

2. Environmental factors: In highly corrosive environments, hot air type cable trays and aluminum alloy cable trays should be selected. At the same time, factors such as wind and snow loads that may be encountered during outdoor installation also need to be considered.

3、橋架規格和尺寸：根據電纜的數量和外徑，計算橋架的填充率和工程發展余量。

3. Bridge specifications and dimensions: Calculate the filling rate and engineering development margin of the bridge based on the number and outer diameter of the cables.

4、支撐和安裝條件：考慮橋架的支撐和安裝的載荷能力以及布置條件，如支撐距離和伸縮縫。如果橋架寬度大于三百毫米，非直線段需要再加一個支撐和一個吊架。

4. Support and installation conditions: Consider the load capacity and layout conditions of the bridge support and installation, such as support distance and expansion joints. If the width of the bridge is greater than 300 millimeters, an additional support and a hanger need to be added to the non-linear section.
