Aluminum alloy cable tray, stainless steel cable tray, FRP cable tray, plastic sprayed cable tray and hot-dip galvanized cable tray all have waterproof and corrosion resistance. Therefore, the commonly known "waterproof bridge" is these five types of bridges. Don't be misunderstood. Think how mysterious the waterproof bridge is and what material it is made of, Xiaobian uses professional industry experience to tell you that for outdoor installation, in order not to be damaged by external factors, such as rain, the following four types of bridges are usually selected before purchasing bridges, so as to clearly understand the construction environment and then select materials. Common specifications of aluminum alloy cable tray are as follows: 80mm * 60MM; 100mm*50mm； 150mm*100mm200mm*100mm300mm*100mm； 400mm*100mm； 400mm*150mm。

對(duì)于跨距大于6m的鋼制電纜橋架和跨距大于2m或承載要求大于荷載等級(jí)D級(jí)的鋁合金電纜橋架，條件應(yīng)該是該項(xiàng)目的實(shí)力，剛度和穩(wěn)定性的計(jì)算或試驗(yàn)驗(yàn)證。全天候產(chǎn)品：產(chǎn)品使用不受海拔高度限制；可長(zhǎng)期在零下40℃的環(huán)境中工作，絕緣樹脂不開裂；可在戶內(nèi)、外高污染等級(jí)（4級(jí)）的環(huán)境中長(zhǎng)期使用。橋架采用鋁合金擠壓成型，尺寸精度高、強(qiáng)度好、外形美觀、重量輕、承載能力大：表面噴砂氧化生成一層天然的氧化保護(hù)膜，對(duì)大氣和化學(xué)介質(zhì)具有很強(qiáng)的耐腐蝕能力：

For steel cable trays with a span of more than 6m and aluminum alloy cable trays with a span of more than 2m or with a bearing requirement greater than load grade D, the condition shall be the calculation or test verification of the strength, stiffness and stability of the project. All weather products: the use of products is not limited by altitude; It can work in the environment of minus 40 ℃ for a long time, and the insulating resin does not crack; It can be used for a long time in indoor and outdoor environment with high pollution level (Level 4). The bridge is extruded with aluminum alloy, with high dimensional accuracy, good strength, beautiful appearance, light weight and large bearing capacity. The surface is sandblasted and oxidized to form a natural oxidation protective film, which has strong corrosion resistance to the atmosphere and chemical media:

按鋁合金電纜橋架承載能力分為：A（輕型）、B（中型）、C（重型）三種；輕、中型*長(zhǎng)4000，重型*長(zhǎng)6000。油浸電纜應(yīng)密封良好，無漏油及滲油現(xiàn)象。其他說明鋁合金電纜橋架功能特點(diǎn):鋁合金電纜橋架有哪些型號(hào)

According to the bearing capacity of aluminum alloy cable tray, it is divided into three types: a (light), B (medium) and C (heavy); light and medium * length 4000 and heavy * length 6000. The oil immersed cable shall be well sealed without oil leakage and oil leakage. Other description of the functional characteristics of aluminum alloy cable tray: what types of aluminum alloy cable tray
