電力電纜橋架材料的分類

電氣安裝工程中，電纜橋架是一個必不可少的部分，其設計的優化程度及橋架材料的選擇，直接關系到電纜橋架的安裝質量。
電纜橋架材料選定：電纜橋架材質有很對，其中最為常見的是金屬電纜橋架，其工藝最為簡單，生產成本比較低，但存在很多缺點：使用壽命
短，容易腐蝕等。從當前的電纜橋架發展來看，在金屬材料基礎上發展起來的有不銹鋼以及碳鋼版，一般彈碳鋼板帶有防腐蝕材料，包括鍍鋅，
噴漆等。
其次是合金塑料電纜橋架。這是一種新型的復合材料，相對魚傳統的金屬電纜橋架，有抗腐蝕，壽命長等優點。
再次是玻璃鋼材料橋架。除了有傳統橋架的剛性外，還有韌性比較好等特點，比較適合惡劣環境及重栽的情況下使用。
最后介紹防火電纜橋架。是一種組火材料配合下的新型復合電纜橋架，其耐火性能可以達到兩個小時。
Classification of material for power cable bridge

The cable bridge is an indispensable part in the electrical installation
 engineering. The optimization of the design and the selection of the material of the bridge are directly related to the
installation quality of the cable bridge.
Cable bridge material selection: the cable bridge frame material is very right,
the most common is the metal cable bridge, its process is the most simple, the production cost is low, but there are many
shortcomings: service life
Short, easy to corrode, etc. From the current development of cable trays, there are stainless
steel and carbon steel plates developed on the basis of metal materials. The commonly used carbon steel plates have
 anticorrosive materials, including galvanizing.
Spray paint and so on.
The next is the alloy plastic cable bridge.
This is a new type of composite material, which has the advantages of corrosion resistance and long service life compared
with traditional fish metal cable tray.
Again, it is a FRP material bridge. In addition to the rigidity of the traditional
 bridge and the good toughness, it is more suitable for the harsh environment and heavy planting.
At last, the bridge frame
 of fire protection cable is introduced. It is a new composite cable bridge with a combination of fire materials and its
fire resistance can reach two hours.
