鋼鋁復合工字型供電軌是傳統供電軌產品，主要用于地鐵、輕軌等傳統城市軌道交通領域，受流方式為上下部受流。與C型軌相同，也是軌道交通中供電系統的 重要部分。組合式供電軌是由鋁合金與銅或不銹鋼組合構成，具有復合供電軌相同的優點，銅、不銹鋼部分可更換，生產工藝相對簡單。
As a traditional power supply rail product, the steel-aluminum composite I-shaped power supply rail is primarily used in the traditional urban rail transit fields such as metro and light rail, etc. and collects current by means of upper and lower current collection. Like the C-rail, it is also an important part of the power supply system in the rail transit. The combined power supply rail is constructed of aluminum alloy and copper or stainless steel and has the advantage of composite power supply rails. With the copper and stainless steel parts replaceable, the production processes are relatively simple.
