01 電纜橋架簡介

　　01 Introduction to Cable Tray

　　電纜橋架作為布線工程的一個配套項目，目前尚無專門的規范指導，每個生產廠家的規格程式缺乏通用性，因此，設計選型過程應根據弱電各個系統纜線的類型、數量，合理選定適用的橋架。可以獨立架設,也可以敷設在各種建(構)筑物和管廊支架上，體現結構簡單、造型美觀、配置靈活和維修方便等特點，全部零件均需進行鍍鋅處理，安裝在建筑物外露天的橋架，如果是在鄰近海邊或屬于腐蝕區，則材質必須具有防腐、耐潮氣、附著力好，耐沖擊強度高的物性特點。

　　As a supporting project of wiring engineering, there is currently no specialized specification guidance for cable trays, and the specifications and programs of each manufacturer lack universality. Therefore, the design and selection process should be based on the type and quantity of cables in various weak current systems, and the appropriate cable tray should be selected reasonably. It can be independently erected or laid on various buildings and pipe gallery supports, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration, and easy maintenance. All parts need to be galvanized and installed on the bridge outside the building. If it is near the seaside or in a corrosive area, the material must have physical properties such as anti-corrosion, moisture resistance, good adhesion, and high impact strength.

　　電纜橋架是由托盤或梯架的直線段、彎通、組件以及托臂（臂式支架）、吊架等構成具有密接支撐電纜的剛性結構系統之全稱。工具/原料：是設計選型、保障的權威技術參考；電纜原材料、電纜附件、電纜設備、電纜橋架、電纜盤具、施工工具、線纜連接器等。

　　Cable tray is a rigid structural system consisting of straight sections, bends, components, as well as support arms (arm brackets), hangers, etc. of trays or ladders that tightly support cables. Tools/raw materials: authoritative technical references for design selection and transaction assurance; Cable raw materials, cable accessories, cable equipment, cable trays, cable reels, construction tools, cable connectors, etc.

　　02 電纜橋架的分類

　　02 Classification of Cable Trays

　　電纜橋架是一款為保護電纜而衍生的產品，是電纜的保護殼，防止電纜受到外界因素的損壞。主要由支架、托臂和安裝附件組成，橋架主要類型可以分為梯式橋架、無孔托盤式橋架（槽式橋架）、有孔托盤式橋架（托盤式電纜橋架）、大跨距電纜橋架等。

　　Cable tray is a product derived from protecting cables, serving as a protective shell for cables to prevent damage from external factors. It mainly consists of brackets, support arms, and installation accessories. The main types of cable trays can be divided into ladder type cable trays, non perforated tray type cable trays (trough type cable trays), perforated tray type cable trays (tray type cable trays), large-span cable trays, etc.

　　▲ 槽式電纜橋架槽式電纜橋架是一種全封閉型的電纜橋架。用整張鋼板彎制而成的槽式部件，其概念上與盤架的區別是高、寬比不同，盤架淺而寬，槽式電纜橋架具有一定的深度和封閉性。

　　▲ Trough type cable tray Trough type cable tray is a fully enclosed cable tray. The difference between a trough type component made by bending a whole steel plate and a tray is the height to width ratio. The tray is shallow and wide, while the trough type cable tray has a certain depth and enclosure.

　　▲ 托盤式電纜橋架托盤式橋架是半密封型，跟鍍鋅槽式橋架的樣子非常相似。托盤式電纜橋架其表面處理可根據用戶需要分為鍍鋅、靜電噴塑和熱鍍鋅三種，在重腐蝕環境中可作特殊防腐處理

　　The tray type cable tray is a semi sealed type, which looks very similar to the galvanized trough type cable tray. The surface treatment of tray type cable trays can be divided into three types according to user needs: galvanizing, electrostatic spraying, and hot-dip galvanizing. Special anti-corrosion treatment can be carried out in heavily corrosive environments

　　▲ 梯式電纜橋架梯式電纜橋架外型像梯子形狀，中間焊有橫桿加固支撐使得重量輕、成本低、承受能力極強、透氣性好；CQ1-T型梯級式電纜橋架根據國內外有關資料改進設計的。

　　▲ Ladder type cable tray The ladder type cable tray is shaped like a ladder, with a horizontal bar welded in the middle to reinforce and support it, making it lightweight, low-cost, highly load-bearing, and breathable; The CQ1-T stepped cable tray has been improved and designed based on relevant domestic and foreign data.

　　▲ 大跨距電纜橋架大跨距電纜橋架一般是由拉擠玻璃鋼型材組裝而成，適用于電力電纜、控制電纜、照明電纜及配件等。

　　▲ Large span cable trays are generally assembled from extruded fiberglass profiles and are suitable for power cables, control cables, lighting cables, and accessories.

　　03 電纜橋架的材質分類

　　03 Classification of Materials for Cable Trays

　　電纜橋架按材質可分類：鍍鋅橋架、不銹鋼橋架、鋁合金橋架、防火橋架、噴塑橋架、熱鍍鋅橋架。

　　Cable trays can be classified by material: galvanized trays, stainless steel trays, aluminum alloy trays, fireproof trays, spray painted trays, and hot-dip galvanized trays.
