电缆桥架要选择什么材质的?

What material should be selected for cable tray
电缆桥架的材质是电缆桥架工程设计常见的另外一个问题。按照材料划分,电缆桥架主要有钢制、玻璃钢和铝合金几种。
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.
该怎样选择电缆桥架材质电缆桥架安装时的支托,是通过立柱和托臂来完成的。立柱是支撑电缆桥架的主要部件;而桥架的荷重是通过托臂传递给立柱的。因此立柱和托臂是电缆桥架安装的两个主要部件,下文主要解析铝合金架、梯形桥架、有孔托盘、无孔托盘相关释义。
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.
铝合金架铝合金制电缆桥架装置的简称,由铝合金材料制作托盘或梯架的直通弯通附件以及支吊架等构成用以支承电缆具有连续刚性结构的总体装置。
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.
梯形桥架梯形电缆桥架直接承托电缆的部件的简称,由两根纵向侧边与若干根横档构成的梯形部件有孔托盘有孔槽形电缆桥架直接承托电缆的部件的简称,由带孔眼的底板和侧边所构成的或由整块铝合金板冲孔后弯曲制成底部有孔的槽形部件无孔托盘无孔槽形电缆桥架直接承托电缆的部件的简称,由底板与侧边构成的或由整块铝合金板弯曲制成实底的槽形部件。
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.
电缆桥架材质的选择玻璃钢电缆桥架的特点是质量轻,比重仅为碳钢的1/4;耐水性和耐腐蚀性好,适合化工厂。不易燃烧,难燃型玻璃钢电缆桥架的氧指数≥32。使用寿命长,一般设计寿命为20年,但价格是钢制电缆桥架的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.
其在施工方面的优越性在于切割方便、组装灵活,安装无需动火,这对于爆炸危险环境并且工程工期紧张的化工厂工程意义尤其重大,因为在爆炸危险环境,工程动火安装时化工厂得停产,经济效益必受影响。
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.
铝合金电缆桥架重量也很轻,由于铝、钢比重不同(Al=2.7,Fe=7.86),按重量计算,铝钢之比约为1:3。铝合金电缆桥架外形尺寸、荷载特性均与钢质桥架基本相近。就费用而言,铝合金桥架的造价比镀锌钢制电缆桥架要高凉城,使用寿命是钢制电缆桥架的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.
