在先进科学技术的现代时代，许多现代工业设施已经出现在我们的世界中并存在于我们的生活中。钢芯铝绞线也是在电力中起重要作用的主要力量。ACSR是由单层或多层铝绞线在镀锌钢芯外部绞合而成的增强钢丝。内部是钢“芯”，外部通过绞合用铝线包裹在钢芯上。; 钢芯主要用于增加强度，铝绞线主要用于传输电能。它在电力和输电线路行业中占有重要地位。对于高压传输线，由于线路的路径有限，因此无法将其安装在一条路径上。对于多行，人们想出了一种使用一条路径，一组铁塔和多根电线的方法，即一条线相当于多条线。对于500KV输电线路，我国大部分地区采用悬挂四根电线的方法。这种接线方法称为同塔并联。这就是为什么某些杆用于“ L J”和“ LGJ”的主要原因。 下面简要介绍一下ACSR的优点和应用。该ACSR具有结构简单，安装，维修方便，低线成本，传输容量大，并且有利于特殊地理条件如杂交河流和沟壑铺设。它具有出色的导电性以及令人满意的机械强度和拉伸强度。高强度和可扩展的塔杆间距等功能。因此，广泛用于各种电压等级的架空输配电线路。 钢芯铝绞线的缩写：“ LGJ”是绞合的铝线和钢丝，普通铝绞线“ L J”主要用于架空输电线路。ACSR的内部为钢“芯”，外部通过绞合用铝线包裹在钢芯上。钢芯主要增加强度，而铝绞线主要传输电能。它们都是裸线，用途基本相同，型号规格不同。 普通铝绞线：型号以“ L J”表示，为裸线。目前，中国一般使用铝包钢绞线（LGJ）作为导体。钢芯主要用于增加强度，铝绞线主要用于传输电能。根据电压的不同，导线的截面积也不同。例如，500 kV传输线的电流导体通常使用LGJ-400 / 35导体。其中，L是铝线的缩写，G是钢芯的缩写，J是绞线的缩写，400是铝的400平方毫米，而35是钢的35平方毫米。
