Five major classification and installation requirements of cable tray:

　　1.槽式電纜橋架

　　1. trough type cable tray

　　槽式電纜橋架是一種全封閉型電纜橋架。它適用于敷設計算機電纜、通信電纜、熱電偶電纜及其他高靈敏系統的控制電纜等。它對控制電纜的屏蔽干擾和重腐蝕中環境電纜的防護都有較好的效果。

　　The trough type cable tray is a fully enclosed cable tray. It is suitable for laying computer cables, communication cables, thermocouple cables and other sensitive system control cables. It has good effect on shielding interference of control cable and protection of environmental cable in heavy corrosion.

　　2.大跨距電纜橋架

　　2. large span cable tray

　　當前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。與鐵制橋架相比，具有使用壽命長(一般設計壽命為二十年)、安裝方便且成本低(比重僅為碳鋼的1/4，施工中無需動火，單根橋架長度可達8米，甚更長)、切割方便、不需維護等優越性。

　　At present, large span cable trays are made of pultruded glass fiber reinforced plastic profiles. They are suitable for power cables, control cables, lighting cables and fittings. Compared with the iron bridge, has the advantages of long service life (general design life of twenty years), convenient installation and low cost (the proportion is only 1/4 carbon steel, no fire, in the construction of a bridge up to 8 meters in length, or even longer), convenient cutting and do not need to maintain the advantages of.

　　3.梯階式電纜橋架

　　3. ladder type cable tray

　　CQ1-T型梯級式電纜橋架是根據國內外有關資料而改進設計的。它具有重量輕、成本低、造型別具、安裝方便、散熱、透氣好等優點。他適用于一般直徑較大電纜的敷設，適合于高、低壓動力電纜的敷設。

　　The CQ1-T ladder type cable tray is designed to improve the design according to the relevant information at home and abroad. The utility model has the advantages of light weight, low cost, different shapes, convenient installation, good heat dissipation, good ventilation, etc.. The utility model is suitable for laying large diameter cables, and is suitable for laying high and low voltage power cables.

　　4.托盤式電纜橋架

　　4. tray type cable tray

　　托盤式電纜橋架是石油、化工、輕工、電訊等方面應用廣泛的一種。它具有重量輕、載荷大、造型美觀、結構簡單、安裝方便等優點。它即適用于動力電纜的安裝，也適合于控制電纜的敷設。

　　Tray type cable tray is one of the most widely used in petroleum, chemical, light industry, telecommunication and other fields. The utility model has the advantages of light weight, large load, beautiful appearance, simple structure, convenient installation, etc.. The utility model is suitable for the installation of power cables, and is also suitable for controlling the laying of cables.

　　5.組合式電纜橋架

　　5. combination type cable bridge frame

　　組合式電纜橋架是一種新型橋架，是電纜橋架系列中的第二代產品。它適用各項工程、各種單位、各種電纜的敷設，它具有結構簡單、配置靈活、安裝方便、形式新穎等特點。

　　The combined cable bridge is a new type of bridge frame, which is the second generation of the cable bridge series. The utility model has the advantages of simple structure, flexible configuration, convenient installation, novel form, etc. the utility model is suitable for the laying of various projects, various units and various cables.
