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。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 the cable tray is another common problem in the design of the cable tray. According to the material division, the cable tray mainly has several kinds of steel, glass fiber reinforced plastic and aluminium alloy.

　　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。

　　Glass fiber reinforced plastic cable bridge is characterized by its light weight and only 1/4 of carbon steel. It has good water resistance and corrosion resistance. It is suitable for chemical plants. Not easy to burn, flame retardant oxygen index = type glass steel cable tray 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)越性在于切割方便、組裝靈活，安裝無需動(dòng)火，這對于爆炸危險(xiǎn)環(huán)境并且工程工期緊張的化工廠工程意義尤其重大，因?yàn)樵诒ㄎｋU(xiǎn)環(huán)境，工程動(dòng)火安裝時(shí)化工廠必須停產(chǎn)，經(jīng)濟(jì)效益必受影響。

　　The service life is long, the general design life is 20 years, but the price is 3 times of the steel cable tray. The superiority of the construction is convenient cutting and flexible assembly, installation without fire, the chemical explosion hazardous environment and engineering significance of plant engineering construction period is especially important, because in the explosion hazardous environment, fire engineering installation of chemical plant must be discontinued, the economic benefit 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，F(xiàn)e=7.86)，按重量計(jì)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(fèi)用而言，鋁合金橋架的造價(jià)比鍍鋅鋼制電纜橋架要高20%，使用壽命是鋼制電纜橋架的5倍以上。

　　Aluminum alloy cable tray weight is very light, due to the different proportion of aluminum and steel (Al=2.7, Fe=7.86), according to weight calculation, the ratio of aluminum steel is about 1:3. The size and load characteristics of aluminum alloy cable bridge are almost the same as those of steel bridge. As far as cost is concerned, the cost of aluminum alloy bridge is 20% higher than that of galvanized steel cable bridge, and the service life is more than 5 times of that of steel cable tray.

　　電纜橋架的表面防腐層類別主要有熱浸鋅、鍍鋅鎳、冷鍍鋅、粉末靜電噴涂等方式，生產(chǎn)廠家資料顯示：熱浸鋅工藝壽命不小于40年，適用于室外重腐蝕環(huán)境，造價(jià)高。

　　The surface anti-corrosion cable tray layer the main categories of hot-dip zinc, nickel plating, cold galvanized, electrostatic powder spraying etc., manufacturer information: life is not less than 40 years of hot galvanizing process, suitable for outdoor heavy corrosion environment, high cost.
