電纜橋架采購之前要懂得哪些“選擇”要點？下面來進行相關的講解吧。

What are the key points of "selection" to know before purchasing cable tray? Let's talk about it.

電纜橋架的材料選擇：一般分為鐵、玻璃鋼、鋁合金和不銹鋼材料，根據不同的施工要求，選擇不同的材料。

Material selection of cable tray: it is generally divided into iron, FRP, aluminum alloy and stainless steel materials. Different materials are selected according to different construction requirements.

電纜橋架表面防腐層的選擇：防腐層是指表面涂層，一般是指它的厚度，通常用來區分熱鍍鋅和鍍鋅板。

Selection of anti-corrosion coating on the surface of cable tray: the anti-corrosion coating refers to the surface coating, generally refers to its thickness, which is usually used to distinguish hot-dip galvanized and galvanized sheet.

電纜橋架防火等級的選擇：目前我國有標準防火等級，允許供應商出示相關文件。

Selection of fire rating of cable tray: at present, there is a standard fire rating in China, and suppliers are allowed to show relevant documents.

電纜橋架的規格尺寸選擇：電纜橋架的施工路線不同，導致規格和尺寸不同。橋梁尺寸是橋梁選擇的重要組成部分。通常，在采購商確定具體規格和數量后，供應商可以提供相應的報價。

Specification and size selection of cable tray: different construction routes of cable tray lead to different specifications and sizes. Bridge size is an important part of bridge selection. Generally, after the purchaser determines the specific specification and quantity, the supplier can provide the corresponding quotation.

電纜橋架填充率的選擇：電纜梯架、托盤寬度和高度的選擇應符合填充率的要求，電纜的梯架和托盤內的填充率在一般情況下，電力電纜可取40%～50%，控制電纜可取50%～70%，且宜預留10%～25%工程發展余量。

Selection of filling rate of cable tray: the width and height of cable ladder and tray shall meet the requirements of filling rate. Generally, the filling rate in cable ladder and tray can be 40% ~ 50% for power cable and 50% ~ 70% for control cable, and 10% ~ 25% engineering development allowance should be reserved.

電纜橋架載荷等級的選擇：在選擇電纜橋架的荷載等級時，電纜橋架的工作均布荷載不應大于所選電纜橋架荷載等級的額定均布荷載，如果電纜橋架的支吊架的實際跨距不等于2m時，則工作均布荷載應滿足要求。各種組件及支吊架在滿足相應荷載的條件下，其規格尺寸應與托盤、梯架的直線段、彎通系列相匹配。

Selection of load grade of cable tray: when selecting the load grade of cable tray, the working uniform load of cable tray shall not be greater than the rated uniform load of the selected load grade of cable tray. If the actual span of supports and hangers of cable tray is not equal to 2m, the working uniform load shall meet the requirements. Under the condition of meeting the corresponding load, the specifications and dimensions of various components, supports and hangers shall match the straight-line section and bend series of trays and ladders.

濟南電纜橋架的廠家選擇：大量采購產品前，一定要注意橋架廠。很多人在做的時候對相關的事情幾乎一無所知，這會直接影響到終的購買質量。制造商會對我們造成很大的影響。尤其是在電纜橋架廠批發中，更要了解廠家，才能真正保證質量。

Manufacturer selection of Jinan cable tray: before purchasing a large number of products, we must pay attention to the cable tray factory. Many people know almost nothing about related things when they do it, which will directly affect the final purchase quality. Manufacturers will have a great impact on us. Especially in the wholesale of cable bridge factory, we should know more about the manufacturer in order to truly ensure the quality.

了解橋架廠，建議有很多事實作為依據。很多人在了解這些東西的時候，就完全脫離了客觀現實，這對于我們了解廠家和產品是非常不利的。只有更加注重方方面面，才能有更多的選擇產品的機會。

To understand the bridge factory, there must be a lot of facts as a basis. When many people understand these things, they are completely divorced from the objective reality, which is very disadvantageous for us to understand the manufacturers and products. Only by paying more attention to all aspects can we have more opportunities to choose products.

在采購電纜橋架的過程中，對所有采購商來說，做好對橋架廠的了解是非常重要的，這樣才能真正保證以后采購時不會出現意外情況。有些人在做事的時候不注意對方，直接影響到后期的購買結果。

In the process of purchasing cable tray, it is very important for all purchasers to understand the cable tray factory well, so as to truly ensure that there will be no accidents in future procurement. Some people do not pay attention to each other when doing things, which directly affects the later purchase results.

還要知道不同型號、不同材質的電纜橋架價格差異很大，結構形式的混亂會給施工現場帶來散熱和機械保護問題。因此，在設計階段，應要求設計人員根據工程環境特點和技術要求，合理選擇電纜橋架的結構特點，并在方案的型號標識和材料清單中明確表達。

We should also know that the prices of cable trays of different models and materials vary greatly, and the confusion of structural form will bring heat dissipation and mechanical protection problems to the construction site. Therefore, in the design stage, designers should be required to reasonably select the structural characteristics of cable tray according to the environmental characteristics and technical requirements of the project, and clearly express them in the model identification and material list of the scheme.
