山東電纜橋架雖然是低壓配電設備中簡單的一種產品，但是它具有品種全、應用廣、結構輕、造價低、外形美觀的特點，給技術改進、電纜擴充、維護檢修帶來方便，在工程中得到廣泛應用，每年的用量相當大。

Although cable tray in Shandong is a simple product of low-voltage distribution equipment, it has the characteristics of complete variety, wide application, light structure, low cost, and beautiful appearance. It brings convenience to technical improvement, cable expansion, maintenance and overhaul, and is widely used in projects, with a considerable amount of consumption every year.

根據制造橋架的材料，橋架一般分為鋼制電纜橋架、阻燃玻璃鋼電纜橋架、抗腐蝕鋁合金電纜橋架、防火電纜橋架四大類。根據橋架的結構形式，橋架一般分為槽式電纜橋架、托盤式電纜橋架、梯階式電纜橋架、組合式電纜橋架、大跨距電纜橋架五大類。這些也是目前在國內應用比較多的橋架，多為封閉型橋架。

According to the materials used to manufacture the cable tray, the cable tray is generally divided into four categories: steel cable tray, flame retardant fiberglass cable tray, corrosion resistant aluminum alloy cable tray, and fire resistant cable tray. According to the structural form of cable tray, cable tray is generally divided into five categories: trough type cable tray, tray type cable tray, ladder type cable tray, combined cable tray, and long-span cable tray. These are also the bridges that are widely used in China, mostly enclosed bridges.

槽式電纜橋架是一中全封閉型電纜橋架，它適用于敷設計算機電纜、通信電纜、熱點偶電纜及其他高靈敏系統的控制電纜的屏蔽干擾和重腐蝕環境中電纜的保護。

The trough type cable tray is a fully enclosed cable tray, which is suitable for laying computer cables, communication cables, hot couple cables and control cables of other highly sensitive systems to shield interference and protect cables in heavily corrosive environments.

托盤式電纜橋架具有質量輕、載荷大、安裝方便等優點，它既適用于動力電纜的安裝，也適用于控制電纜的敷設。梯階式電纜橋架適用于直徑大電纜的敷設，特別適用高、低壓動力電纜的敷設。

Tray type cable tray has the advantages of light weight, large load, convenient installation, etc. It is suitable for the installation of power cables and the laying of control cables. Ladder type cable tray is suitable for laying large diameter cables, especially for laying high and low voltage power cables.

組合式電纜橋架能夠根據安裝場所的實際情況，隨意組合，適用于安裝環境較為復雜，對橋架走線槽空間變化有較多要求的場合。

The combined cable tray can be combined at will according to the actual situation of the installation site, and is suitable for occasions where the installation environment is more complex and there are more requirements for the space change of cable tray trunking.

大跨距電纜橋架受安裝場所條件限制，不能設置較多托臂、吊架、要求橋架必須要有較大支吊跨距的場合。

The large span cable tray is limited by the installation site conditions, so it is not allowed to set many corbels and hangers. It is required that the bridge must have a large span of supports and hangers.

選擇橋架需要考慮兩個重要指標：電纜橋架的承載能力應滿足工作均布載荷小于額定均布載荷，電纜橋架應能適用不同的環境要求和有較長的適用壽命。電纜橋架的承載能力是通過選擇適當厚度的材料來滿足，環境要求和適用壽命是通過選擇相應的原材料來滿足。

Two important indicators need to be considered when selecting cable tray: the bearing capacity of cable tray should meet the requirement that the working uniform load is less than the rated uniform load, and cable tray should be able to meet different environmental requirements and have a long service life. The bearing capacity of cable tray is met by selecting materials with appropriate thickness, and the environmental requirements and applicable life are met by selecting corresponding raw materials.

為了提高電纜橋架的承載能力，一般是增加橋架的板材厚度來實現的；而環境要求則是重腐蝕環境一般選用玻璃鋼或者鋁合金作為生產電纜橋架的主體材料，常規腐蝕環境一般選用鋼質材料作為生產電纜橋架的主體材料，而鋼質電纜橋架根據橋架的耐腐蝕等級又分別采用熱浸鍍鋅，熱固體粉末靜電噴塑、噴漆、電鍍鋅等表面處理方式。更多事項就來我們網站http://www.yeeones.com咨詢了解吧！

In order to improve the bearing capacity of cable tray, it is generally realized by increasing the plate thickness of the bridge; The environmental requirement is that glass fiber reinforced plastic or aluminum alloy is generally used as the main material for cable tray production in heavily corrosive environment, and steel material is generally used as the main material for cable tray production in conventional corrosive environment, while steel cable tray adopts hot dip galvanizing, hot solid powder electrostatic spraying, painting, galvanization and other surface treatment methods according to the corrosion resistance grade of the bridge.
