如果您在有防火要求的路段購買電纜橋架，可以在電纜梯的橋架上添加防火或阻燃的板、網(wǎng)等材料。形成密閉或半密閉結(jié)構(gòu)，采取在橋梁及其支吊架表面涂刷防火涂料等措施，達(dá)到防火要求。

If you buy cable trays in sections with fire protection requirements, you can add fireproof or flame-retardant plates, nets and other materials to the cable ladder trays. Form a closed or semi closed structure, and take measures such as painting fireproof paint on the surface of the bridge and its supports and hangers to meet the fire protection requirements.

如果要在腐蝕環(huán)境中使用，應(yīng)采用耐腐蝕的剛性材料制成或經(jīng)過防腐處理。防腐處理方法應(yīng)符合工程環(huán)境要求。環(huán)境和耐久性要求。如果有電纜線或油、腐蝕性液體、易燃粉塵等環(huán)境要求需要屏蔽電磁干擾。

If it is to be used in corrosive environment, it shall be made of corrosion-resistant rigid materials or treated with corrosion protection. The anti-corrosion treatment method shall meet the environmental requirements of the project. Environmental and durability requirements. If there are environmental requirements such as cable or oil, corrosive liquid, flammable dust, etc., electromagnetic interference shall be shielded.

在工程設(shè)計(jì)文件中，電纜橋架一般簡稱為“橋架”，并沒有指出具體的結(jié)構(gòu)特點(diǎn)、不同類型和材料的電纜橋架。差異大，結(jié)構(gòu)類型的混亂會(huì)帶來工作場所的散熱和機(jī)械保護(hù)方面的問題。因此，在設(shè)計(jì)階段，應(yīng)要求設(shè)計(jì)者應(yīng)根據(jù)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)，并在方案的型號標(biāo)識和材料表中明確表示。

In the engineering design documents, the cable tray is generally referred to as "tray", and the specific structural characteristics, different types and materials of cable tray are not indicated. Large price differences and confusion of structural types will bring problems in heat dissipation and mechanical protection in the workplace. Therefore, in the design stage, the designer shall be required to reasonably select the structural characteristics of the cable tray according to the characteristics and technical requirements, and clearly indicate them in the model identification and material list of the scheme.

電纜橋架的材料是電纜橋架工程設(shè)計(jì)中的另一個(gè)常見問題。按材質(zhì)分，電纜橋架主要由鋼材、玻璃鋼和鋁材制成。玻璃鋼電纜橋架的特點(diǎn)是重量輕，比重僅為碳鋼的1/4；良好的耐水性和耐腐蝕性，適用于化工廠。不易燃、阻燃的玻璃鋼電纜橋架支架氧指數(shù)≥32。使用壽命長，一般設(shè)計(jì)壽命為20年，但是鋼制電纜橋架的3倍。施工的優(yōu)點(diǎn)在于切割方便，組裝靈活。

The material of cable tray is another common problem in cable tray engineering design. According to the material, the cable tray is mainly made of steel, FRP and aluminum. 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. Oxygen index of non flammable and flame retardant FRP cable tray support ≥ 32. The service life is long. The general design life is 20 years, but the price is 3 times that of steel cable tray. The construction has the advantages of convenient cutting and flexible assembly.

對于爆炸性危險(xiǎn)環(huán)境下的化工廠項(xiàng)目意義重大，一期工程緊張，因?yàn)樵诒ㄐ晕ｋU(xiǎn)環(huán)境下，項(xiàng)目的熱裝是不必要的。當(dāng)化工廠必須停產(chǎn)時(shí)，經(jīng)濟(jì)效益就會(huì)受到影響。鋁合金電纜橋架重量也很輕。由于鋁和鋼的比重不同（Al=2.7，F(xiàn)e=7.86），以重星計(jì)算。經(jīng)計(jì)算，鋁與鋼的比例約為1：3。鋁制電纜橋架的尺寸和負(fù)載特性與鋼制橋架基本相似。在成本方面，鋁合金橋架的成本高于電鍍鋅鋼橋架高出20%，使用壽命是鋼橋架的5倍以上。

It is of great significance for the chemical plant project in explosive hazardous environment, and the phase I project is tense, because the hot charging of the project is unnecessary in explosive hazardous environment. When the chemical plant has to stop production, the economic benefit will be affected. The weight of aluminum alloy cable tray is also very light. Since the specific gravity of aluminum and steel is different (al=2.7, fe=7.86), it is calculated by heavy star. After calculation, the ratio of aluminum to steel is about 1:3. The size and load characteristics of aluminum cable tray are basically similar to those of steel cable tray. In terms of cost, the cost of aluminum alloy bridge is 20% higher than that of galvanized steel bridge, and its service life is more than 5 times that of steel bridge.

電纜橋架的種類很多，大多數(shù)電纜橋架由支架、支撐臂、安裝附件等組成。零部件必須滿足標(biāo)準(zhǔn)化、通用化、系列化的要求，以方便日后的維護(hù)和維修。此外，還要確定電纜橋架的形狀和結(jié)構(gòu)是否美觀，是否合理，配置是否靈活應(yīng)考慮。由于電纜橋架一般安裝在室外，因此周圍環(huán)境的特點(diǎn)也是重要的因素。

There are many kinds of cable trays, most of which are composed of brackets, support arms, installation accessories, etc. Parts must meet the requirements of standardization, generalization and serialization to facilitate future maintenance and repair. In addition, it is necessary to determine whether the shape and structure of the cable tray are beautiful, reasonable and flexible. Since cable trays are generally installed outdoors, the characteristics of the surrounding environment are also important factors.

這是為了電纜橋架的耐腐蝕性、耐濕性和附著力性能起著關(guān)重要的作用。總而言之，濟(jì)南電纜橋架廠家建議您必須選擇正確的電纜橋架購買才行。更多內(nèi)容來網(wǎng)站m.ymmgjx.net關(guān)注咨詢吧！

This is to play a crucial role in the corrosion resistance, humidity resistance and adhesion performance of cable tray. In a word, Jinan cable tray manufacturer suggests that you must choose the right cable tray to buy.
