供電軌（又稱導電軌、接觸軌），是軌道交通中供電系統的重要部分，是城市地鐵、輕軌以及磁懸浮列車等軌道交通的電能傳輸重要部件,它對列車的高速運行、安全可靠性等都起著十分重要的作用?？蓮V泛用于地鐵、高鐵、輕軌、磁懸浮等軌道交通供電系統中。
　　C型鋼鋁復合供電軌（簡稱C型軌）是一種新型的鋼鋁復合供電軌，與傳統的工字型供電軌相比較，具有如下等優點，在道岔區能夠實現完全彈性彎曲，特別適合于各種坡度大、彎道急等地形復雜的高架線路，也是未來城市磁懸浮交通首選的供電軌軌型。
　　C型鋼鋁復合導電軌主要優越性在于：
　　1) 有效軌面寬度大，適合側向受流和上下受流，鋼鋁復合面結合強度高；
　　2) 彈性變形量大、允許的彈性變形半徑較??；
　　3) 安裝方便、快捷，所需要的安裝操作空間較小，可以實現機械化安裝操作, 安裝精度高、簡便快捷、施工成本低；
　　我公司研發生產的C型鋼鋁復合供電軌是在德國同類產品基礎上，通過結構改進所研發的具有自主知識產權的新一代C型軌，復合結合強度高，達到9.5KN/cm（軌長），高于德國同類產品的8.5KN/cm（軌長）?？傮w性能達到國際先進水平。

As a new type of steel-aluminum composite power supply rail, the C-shaped steel-aluminum composite power supply rail (hereinafter referred to as the C-rail) has the following advantages, compared with the traditional I-shaped power supply rail: It can realize complete elastic bending in the turnout area, is particularly suitable for various topographically complicated elevated lines with large grade and abrupt curve and is also the preferred power supply rail type for the future urban maglev traffic.
The main superiorities of the C-shaped steel-aluminum composite conductor rail lie in:
1) Large effective rail surface width, suitable for lateral current collection as well as upper and lower current collection and high bond strength of steel-aluminum composite surface;
2) Large elastic deformation and small allowable elastic deformation radius;
3) Installation convenience and rapidness, small required installation operating space, reliability of mechanized installation operations, high installation accuracy, installation ease and low construction cost;
The C-shaped steel-aluminum composite power supply rail researched & developed and produced by our Company is a new generation of C-rail with independent intellectual property rights researched and developed through structural improvement on the basis of similar German products and has a high composite bond strength, up to 9.5KN/cm (rail length), higher than that (8.5KN/cm (rail length)) of similar German products. The overall performances reach the international advanced level.
This product has been granted the patent for invention .
