在设计用于腐蚀性或室外环境的电缆桥架系统时，重要的选择之一是材料。具有热浸镀锌涂层的钢制电缆桥架已经被使用了很多年，在当今建筑预算缩减的今天，铝合金电缆桥架的初始成本通常会比热浸镀锌钢制电缆桥架高的情况下，为什么工程师、承包商和终用户会选择铝合金电缆桥架呢？

When designing cable tray systems for corrosive or outdoor environments, one of the important choices is materials. The steel cable tray with hot-dip galvanized coating has been used for many years. Today, when the construction budget is reduced, the initial cost of aluminum alloy cable tray is usually higher than that of hot-dip galvanized steel cable tray. Why do engineers, contractors and end users choose aluminum alloy cable tray?

山东电缆桥架厂家认为其答案在于铝在安装生命周期中在设计，安装，交付，性能和总成本方面的诸多优势。

Shandong cable tray manufacturers believe that the answer lies in the advantages of aluminum in design, installation, delivery, performance and total cost in the installation life cycle.

设计安装

Design and installation

大多数人都知道铝具有很好的强度重量比。例如，梯形电缆桥架的36英寸宽，24英尺长，侧轨为6英寸的NEMA 20C热浸镀锌钢电缆桥架重约200磅，而铝制的相同电缆桥架重约100磅。

Most people know that aluminum has a good strength to weight ratio. For example, the 36 inch wide, 24 foot long, 6-inch side rail NEMA 20C hot-dip galvanized steel cable tray of trapezoidal cable tray weighs about 200 pounds, while the same aluminum cable tray weighs about 100 pounds.

当安装人员必须将电缆托架部分提起并放置到距离地面30英尺或30英尺以上的位置时，铝的重量更轻意味着可以只需要两个安装者，而不是四个安装者。

When the installation personnel must lift and place the cable tray section 30 feet or more above the ground, the lighter weight of aluminum means that only two installers are needed instead of four.

铝合金电缆桥架更容易进行现场切割、打孔和钻孔，无需在裸露的边缘上涂保护层。当使用电缆桥架作为设备接地导体时，铝的好的载流能力减少了购买和安装单独的（在合格的工业安装中）的需要，并且通过提供更好的故障电流路径而增加了安装的安全性。

The aluminum alloy cable tray is easier to cut, punch and drill on site, and there is no need to apply protective layer on the exposed edge. When cable tray is used as equipment grounding conductor, the good current carrying capacity of aluminum reduces the need to purchase and install separate (in qualified industrial installation), and increases the safety of installation by providing a better fault current path.

优良性能

Excellent performance

由于铝合金电缆桥架组件是挤压成型的，因此可以更有效地利用材料。型材表面喷砂氧化有一层自然的氧化保护膜，对大气和化学介质具有很强的耐侵蚀能力。

As aluminum alloy cable tray components are extruded, materials can be used more effectively. The surface of the profile is sandblasted and oxidized with a natural oxidation protective film, which has strong corrosion resistance to atmospheric and chemical media.

钢制电缆桥架上的镀锌设计可缓慢磨损，因为它可以保护钢。涂层薄或已经没有涂层的任何地方都会限制产品的使用寿命。

The galvanized design on the steel cable tray can wear slowly because it can protect the steel. Thin coating or no coating anywhere will limit the service life of the product.

而铝合金电缆桥架始终是均质材料，因此其使用寿命不受刮擦和现场修改的影响。当铝合金电缆桥架与不锈钢硬件一起使用时，该系统可以无限期地运行，其性能随着时间的推移几乎不会降级，使其成为许多化学和海洋环境的理想选择。

The aluminum alloy cable tray is always a homogeneous material, so its service life is not affected by scratch and on-site modification. When aluminum alloy cable tray is used together with stainless steel hardware, the system can operate indefinitely, and its performance will hardly degrade over time, making it an ideal choice for many chemical and marine environments.

铝的许多有利功能，例如其耐腐蚀性能、优异的强度重量比、易于现场修改、快速交付和可用性以及省力的安装，所有这些都使得铝合金电缆桥架在长期成本方面具有优势。所以说，如果您对此有需求或者哪方面有疑惑，可以随时来我们网站 //www.comprepyme.com留言哦！
