電纜橋架和鋼制橋架有什么區(qū)別？

What is the difference between cable tray and steel tray?

在相同規(guī)格下，阻燃型電纜橋架比鋼制電纜橋架貴2.2倍，使用壽命是鋼制電纜橋架的5倍以上，重量比鋼制電纜橋架重30%。防火型電纜橋架比鋼制電纜橋架稍貴，使用壽命是鋼制電纜橋架的3倍以上，重量與鋼制電纜橋架基本相同。

Under the same specification, flame retardant cable tray is 2.2 times more expensive than steel cable tray, its service life is more than 5 times that of steel cable tray, and its weight is 30% heavier than steel cable tray. The fireproof cable tray is slightly more expensive than the steel cable tray. Its service life is more than 3 times that of the steel cable tray, and its weight is basically the same as that of the steel cable tray.

電纜橋架類型型號(hào)有哪些？

What are the types and models of cable trays?

山東電纜橋架類型型號(hào)主要分為：槽式、梯式、托盤式等，具體比如：

Shandong cable tray types and models are mainly divided into: trough type, ladder type, tray type, etc., for example:

槽式電纜橋架：槽式電纜橋架是一種全封閉型的電纜橋架。適用于敷設(shè)計(jì)算機(jī)電纜、通信電纜、熱電偶電纜及其他高靈敏系統(tǒng)的控制電纜等。它對(duì)控制電纜的屏蔽干擾和重腐蝕環(huán)境中電纜的防護(hù)都有較好的效果。

Trough type cable tray: the trough type cable tray is a fully enclosed cable tray. It is suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has good effect on shielding interference of control cable and cable protection in heavy corrosive environment.

梯式電纜橋架：外型像梯子形狀，中間焊有橫桿加固支撐使得重量輕、成本低、承受能力極強(qiáng)、透氣性好，一般直徑比較大的電纜和高、低動(dòng)力電纜的敷設(shè)都會(huì)使用到。

Ladder type cable tray: it is shaped like a ladder, and a cross bar is welded in the middle for reinforcement and support, which makes it light in weight, low in cost, strong in bearing capacity and good in air permeability. It is generally used for the laying of cables with large diameter and high and low power cables.

托盤式電纜橋架：托盤式橋架是半密封型，它跟鍍鋅槽式橋架的樣子非常相似，它具有重量輕、載荷大、造型美觀、結(jié)構(gòu)簡(jiǎn)單、安裝方便等優(yōu)點(diǎn)。

Tray type cable tray: tray type cable tray is a semi sealed type, which is very similar to the galvanized trough type cable tray. It has the advantages of light weight, large load, beautiful appearance, simple structure and convenient installation.

電纜橋架工程設(shè)計(jì)需要注意什么？

What should be paid attention to in cable tray engineering design?

在工程設(shè)計(jì)文件中通常籠統(tǒng)地將電纜橋架稱呼為“橋架”，并未指出具體的結(jié)構(gòu)特征，不同類型、不同制作材料的電纜橋架相差較大，且結(jié)構(gòu)類型的混亂會(huì)帶來工作現(xiàn)場(chǎng)散熱、機(jī)械防護(hù)方面的問題。

In the engineering design documents, the cable tray is generally referred to as "tray", and the specific structural characteristics are not pointed out. The prices of cable trays of different types and materials vary greatly, and the confusion of structural types will bring problems in heat dissipation and mechanical protection at the work site.

故在設(shè)計(jì)階段應(yīng)要求設(shè)計(jì)人員根據(jù)工程環(huán)境特征和技術(shù)要求，合理選擇電纜橋架的結(jié)構(gòu)特征，并在平面圖的型號(hào)標(biāo)注和材料表中進(jìn)行清晰地表達(dá)。電纜橋架的材質(zhì)是電纜橋架工程設(shè)計(jì)常見的另外一個(gè)問題。

Therefore, in the design stage, the designer shall be required to reasonably select the structural features of the cable tray according to the environmental characteristics and technical requirements of the project, and clearly express them in the model annotation and material list of the plan. The material of cable tray is another common problem in cable tray engineering design.

按照材料劃分，電纜橋架主要有鋼制、玻璃鋼和鋁合金幾種。玻璃鋼電纜橋架的特點(diǎn)是質(zhì)量輕，比重僅為碳鋼的1/4；耐水性和耐腐蝕性好，適合化工廠。不易燃燒，難燃型玻璃鋼電纜橋架的氧指數(shù)≥32。使用壽命長(zhǎng)，一般設(shè)計(jì)壽命為20年，但是鋼制電纜橋架的3倍。

According to the classification of materials, cable trays mainly include steel, FRP and aluminum alloy. Fiberglass reinforced plastic cable tray is characterized by light weight, and its specific gravity is only 1/4 of that of carbon steel; Good water resistance and corrosion resistance, suitable for chemical plants. It is not easy to burn, and the oxygen index of fire-resistant FRP cable tray is ≥ 32. The service life is long. The general design life is 20 years, but the price is 3 times that of steel cable tray.

弱電電纜與其它低電壓電纜合用橋架時(shí)應(yīng)注意什么？

What should be paid attention to when the weak current cable and other low voltage cables share the bridge?

山東電纜橋架廠家認(rèn)為，弱電電纜與其它低電壓電纜合用橋架時(shí),應(yīng)嚴(yán)格執(zhí)行選擇具有外屏蔽層的弱電系統(tǒng)的弱電電纜,避免相互間的干擾。比如電纜橋架由室外進(jìn)入建筑物內(nèi)時(shí),橋架向外的坡度不得小于1/100。

Shandong cable tray manufacturer believes that when the weak current cable and other low-voltage cables share the tray, the weak current cable of the weak current system with external shielding layer shall be strictly selected to avoid mutual interference. For example, when the cable tray enters the building from the outside, the outward slope of the tray shall not be less than 1/100.
