電纜的出現(xiàn)很大程度的解決了帶長距離輸電的問題，有需求就有供求，這是連鎖反應(yīng)，橋架也因此成為非常受歡迎的設(shè)備，不過在選購的時候不能盲目的跟從，而是需要我們依據(jù)自己的實際需要進(jìn)行選擇。

The emergence of cables has greatly solved the problem of long-distance power transmission. When there is demand, there is supply and demand. This is a chain reaction, and cable trays have become very popular equipment. However, when choosing, we cannot blindly follow, but need to choose according to our actual needs.

電纜橋架選購要點：

Key points for selecting cable trays:

1、母線槽廠家介紹在工程設(shè)計中，電纜橋架的布置應(yīng)根據(jù)經(jīng)濟(jì)合理性、技術(shù)可行性、運行安全性等因素綜合比較，以確定合適的方案，還要充分滿足施工安裝、維護(hù)檢修及電纜敷設(shè)的要求。

1. Bus duct manufacturers introduce that in engineering design, the layout of cable trays should be comprehensively compared based on factors such as economic rationality, technical feasibility, and operational safety to determine a suitable plan. It should also fully meet the requirements of construction, installation, maintenance, and cable laying.

2、電纜橋架水平敷設(shè)時距地面的高度一般不低于于2.5m，垂直敷設(shè)時距地面1.8m以下部分應(yīng)加金屬蓋板保護(hù)，但敷設(shè)在電氣專用房間內(nèi)時除外。電纜橋架水平敷設(shè)在設(shè)備夾層或上人馬道且低于2.5m，應(yīng)采取保護(hù)接地措施。

2. When the cable tray is laid horizontally, the height above the ground is generally not less than 2.5m. When laid vertically, the part below 1.8m above the ground should be protected with a metal cover plate, except when laid in an electrical dedicated room. When the cable tray is horizontally laid in the equipment interlayer or on the pedestrian walkway and is less than 2.5m, protective grounding measures should be taken.

3、電纜橋架、線槽及其支吊架使用在有腐蝕性環(huán)境中，應(yīng)采用耐腐蝕的剛性材料制造.或采取防腐蝕處理，防腐蝕處理方式應(yīng)滿足環(huán)境和耐久性的要求。對耐腐蝕性能要求較高或要求潔凈的場所，宜選用鋁合金電纜橋架。

3. Cable trays, trunking, and their supports and hangers should be made of corrosion-resistant rigid materials when used in corrosive environments Alternatively, anti-corrosion treatment can be adopted, and the anti-corrosion treatment method should meet the requirements of the environment and durability. Aluminum alloy cable trays are recommended for places with high requirements for corrosion resistance or cleanliness.

4、纜橋架品種的選擇分為幾種情況，在有易燃粉塵的場所或者是需要屏蔽外部的電氣干擾，要采用無孔托盤；高溫、腐蝕性液體或油的濺落等需要防護(hù)場所，要采用托盤；需要根據(jù)情況去組裝電纜橋架的時候，可用組裝時托盤；除了剛講的幾個情況，其他情況都可以采用梯架。

4. The selection of cable tray types can be divided into several situations. In places with flammable dust or where external electrical interference needs to be shielded, perforated trays should be used; In places where high temperature, corrosive liquids or oil splashes require protection, pallets should be used; When assembling cable trays according to the situation, assembly trays can be used; Except for the situations mentioned earlier, ladder frames can be used in all other situations.
