在設計用于腐蝕性或室外環(huán)境的電纜橋架系統(tǒng)時，重要的選擇之一是材料。具有熱浸鍍鋅涂層的鋼制電纜橋架已經被使用了很多年，在當今建筑預算縮減的今天，鋁合金電纜橋架的初始成本通常會比熱浸鍍鋅鋼制電纜橋架高的情況下，為什么工程師、承包商和終用戶會選擇鋁合金電纜橋架呢？

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?

山東電纜橋架廠家認為其答案在于鋁在安裝生命周期中在設計，安裝，交付，性能和總成本方面的諸多優(yōu)勢。

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.

設計安裝

Design and installation

大多數(shù)人都知道鋁具有很好的強度重量比。例如，梯形電纜橋架的36英寸寬，24英尺長，側軌為6英寸的NEMA 20C熱浸鍍鋅鋼電纜橋架重約200磅，而鋁制的相同電纜橋架重約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.

當安裝人員必須將電纜托架部分提起并放置到距離地面30英尺或30英尺以上的位置時，鋁的重量更輕意味著可以只需要兩個安裝者，而不是四個安裝者。

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.

鋁合金電纜橋架更容易進行現(xiàn)場切割、打孔和鉆孔，無需在裸露的邊緣上涂保護層。當使用電纜橋架作為設備接地導體時，鋁的好的載流能力減少了購買和安裝單獨的（在合格的工業(yè)安裝中）的需要，并且通過提供更好的故障電流路徑而增加了安裝的性。

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.

優(yōu)良性能

Excellent performance

由于鋁合金電纜橋架組件是擠壓成型的，因此可以更有效地利用材料。型材表面噴砂氧化有一層自然的氧化保護膜，對大氣和化學介質具有很強的耐侵蝕能力。

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.

鋼制電纜橋架上的鍍鋅設計可緩慢磨損，因為它可以保護鋼。涂層薄或已經沒有涂層的任何地方都會限制產品的使用壽命。

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.

而鋁合金電纜橋架始終是均質材料，因此其使用壽命不受刮擦和現(xiàn)場修改的影響。當鋁合金電纜橋架與不銹鋼硬件一起使用時，該系統(tǒng)可以無限期地運行，其性能隨著時間的推移幾乎不會降級，使其成為許多化學和海洋環(huán)境的理想選擇。

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.

鋁的許多有利功能，例如其耐腐蝕性能、優(yōu)異的強度重量比、易于現(xiàn)場修改、快速交付和可用性以及省力的安裝，所有這些都使得鋁合金電纜橋架在長期成本方面具有優(yōu)勢。所以說，如果您對此有需求或者哪方面有疑惑，可以隨時來我們網站http://m.ymmgjx.net留言哦！
