電纜橋架采購(gòu)之前要懂得哪些“選擇”要點(diǎn)？下面來(lái)進(jìn)行相關(guān)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(jù)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(lái)區(qū)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(jí)的選擇：目前我國(guó)有標(biāo)準(zhǔn)防火等級(jí)，允許供應(yīng)商出示相關(guān)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(guī)格尺寸選擇：電纜橋架的施工路線不同，導(dǎo)致規(guī)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(gòu)商確定具體規(guī)格和數(shù)量后，供應(yīng)商可以提供相應(yīng)的報(bào)價(jià)。

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(yīng)符合填充率的要求，電纜的梯架和托盤內(nèi)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(yù)留10%～25%工程發(fā)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(jí)的選擇：在選擇電纜橋架的荷載等級(jí)時(shí)，電纜橋架的工作均布荷載不應(yīng)大于所選電纜橋架荷載等級(jí)的額定均布荷載，如果電纜橋架的支吊架的實(shí)際跨距不等于2m時(shí)，則工作均布荷載應(yīng)滿足要求。各種組件及支吊架在滿足相應(yīng)荷載的條件下，其規(guī)格尺寸應(yīng)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(jì)南電纜橋架的廠家選擇：大量采購(gòu)產(chǎn)品前，一定要注意橋架廠。很多人在做的時(shí)候?qū)ο嚓P(guān)的事情幾乎一無(wú)所知，這會(huì)直接影響到終的購(gòu)買質(zhì)量。制造商會(huì)對(duì)我們?cè)斐珊艽蟮挠绊憽Ｓ绕涫窃陔娎|橋架廠批發(fā)中，更要了解廠家，才能真正保證質(zhì)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，必須有很多事實(shí)作為依據(jù)。很多人在了解這些東西的時(shí)候，就完全脫離了客觀現(xiàn)實(shí)，這對(duì)于我們了解廠家和產(chǎn)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(chǎn)品的機(jī)會(huì)。

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(gòu)電纜橋架的過程中，對(duì)所有采購(gòu)商來(lái)說，做好對(duì)橋架廠的了解是非常重要的，這樣才能真正保證以后采購(gòu)時(shí)不會(huì)出現(xiàn)意外情況。有些人在做事的時(shí)候不注意對(duì)方，直接影響到后期的購(gòu)買結(jié)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(hào)、不同材質(zhì)的電纜橋架差異很大，結(jié)構(gòu)形式的混亂會(huì)給施工現(xiàn)場(chǎng)帶來(lái)散熱和機(jī)械保護(hù)問題。因此，在設(shè)計(jì)階段，應(yīng)要求設(shè)計(jì)人員根據(jù)工程環(huán)境特點(diǎn)和技術(shù)要求，合理選擇電纜橋架的結(jié)構(gòu)特點(diǎn)，并在方案的型號(hào)標(biāo)識(shí)和材料清單中明確表達(dá)。

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.
