電纜橋架要選擇什么材質(zhì)的?

What material should be selected for cable tray
電纜橋架的材質(zhì)是電纜橋架工程設計常見(jiàn)的另外一個(gè)問(wèn)題。按照材料劃分,電纜橋架主要有鋼制、玻璃鋼和鋁合金幾種。
The material of cable tray is another common problem in cable tray engineering design. According to the classification of materials, cable trays mainly include steel, FRP and aluminum alloy.
該怎樣選擇電纜橋架材質(zhì)電纜橋架安裝時(shí)的支托,是通過(guò)立柱和托臂來(lái)完成的。立柱是支撐電纜橋架的主要部件;而橋架的荷重是通過(guò)托臂傳遞給立柱的。因此立柱和托臂是電纜橋架安裝的兩個(gè)主要部件,下文主要解析鋁合金架、梯形橋架、有孔托盤(pán)、無(wú)孔托盤(pán)相關(guān)釋義。
How to select the material of the cable tray? The support during the installation of the cable tray is completed through the column and support arm. The column is the main component supporting the cable tray; The load of the bridge is transmitted to the column through the bracket. Therefore, the column and bracket are the two main components of cable tray installation. The following mainly analyzes the relevant definitions of aluminum alloy frame, trapezoidal tray, perforated tray and non perforated tray.
鋁合金架鋁合金制電纜橋架裝置的簡(jiǎn)稱(chēng),由鋁合金材料制作托盤(pán)或梯架的直通彎通附件以及支吊架等構成用以支承電纜具有連續剛性結構的總體裝置。
Aluminum alloy frame is the abbreviation of aluminum alloy cable tray device, which is composed of straight through bending accessories and supports and hangers of tray or ladder made of aluminum alloy material to support the overall device with continuous rigid structure of cable.
梯形橋架梯形電纜橋架直接承托電纜的部件的簡(jiǎn)稱(chēng),由兩根縱向側邊與若干根橫檔構成的梯形部件有孔托盤(pán)有孔槽形電纜橋架直接承托電纜的部件的簡(jiǎn)稱(chēng),由帶孔眼的底板和側邊所構成的或由整塊鋁合金板沖孔后彎曲制成底部有孔的槽形部件無(wú)孔托盤(pán)無(wú)孔槽形電纜橋架直接承托電纜的部件的簡(jiǎn)稱(chēng),由底板與側邊構成的或由整塊鋁合金板彎曲制成實(shí)底的槽形部件。
Trapezoidal tray trapezoidal cable tray is the abbreviation of the part that directly supports the cable. It is the abbreviation of the trapezoidal part that consists of two longitudinal sides and several rungs. The perforated tray is the abbreviation of the part that directly supports the cable, The abbreviation of the part that is composed of a bottom plate with holes and side edges, or the grooved part with holes at the bottom is made by punching and bending the whole aluminum alloy plate. The non perforated tray non perforated grooved cable bridge directly supports the cable, and the grooved part that is composed of a bottom plate and side edges, or the solid bottom is made by bending the whole aluminum alloy plate.
電纜橋架材質(zhì)的選擇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(chǎng)。不易燃燒,難燃型玻璃鋼電纜橋架的氧指數≥32。使用壽命長(cháng),一般設計壽命為20年,但是鋼制電纜橋架的3倍。
Selection of cable tray material FRP cable tray is characterized by light weight and the 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 flame retardant 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.
其在施工方面的優(yōu)越性在于切割方便、組裝靈活,安裝無(wú)需動(dòng)火,這對于爆炸危險環(huán)境并且工程工期緊張的化工廠(chǎng)工程意義尤其重大,因為在爆炸危險環(huán)境,工程動(dòng)火安裝時(shí)化工廠(chǎng)得停產(chǎn),經(jīng)濟效益必受影響。
Its advantages in construction are convenient cutting, flexible assembly and no hot work for installation, which is of great significance for the chemical plant with explosive hazardous environment and tight construction period, because in the explosive hazardous environment, the chemical plant has to stop production during hot work installation, and the economic benefits will be affected.
鋁合金電纜橋架重量也很輕,由于鋁、鋼比重不同(Al=2.7,Fe=7.86),按重量計算,鋁鋼之比約為1:3。鋁合金電纜橋架外形尺寸、荷載特性均與鋼質(zhì)橋架基本相近。就費用而言,鋁合金橋架的造價(jià)比鍍鋅鋼制電纜橋架要高涼城,使用壽命是鋼制電纜橋架的5倍以上。
The weight of aluminum alloy cable tray is also very light. Due to the different specific gravity of aluminum and steel (al = 2.7, Fe = 7.86), the ratio of aluminum to steel is about 1:3 according to the weight. The overall dimensions and load characteristics of aluminum alloy cable tray are basically similar to those of steel cable tray. In terms of cost, the cost of aluminum alloy cable tray is higher than that of galvanized steel cable tray, and the service life of Liangcheng is more than 5 times that of steel cable tray.
