Description
技术领域
本发明属于电缆，尤其涉及一种架空电缆。
背景技术
在输电线路中，经常使用的架空电缆线是钢绞线，这主要是因为钢绞线具有较好的抗拉性能，但与铜、铝等金属相比，钢的导电性能要差一些。
发明内容
本发明的目的是提供一种既具有较好导电性能又具有较好抗拉性能的架空电缆。
为实现上述目的，本发明采用如下技术方案：一种架空电缆，包括一根圆芯线，所述的芯线为铝包钢芯导线，芯线外绞合有圆铝合金导线。
所述的铝合金导线至少有六根。
采用上述技术方案的架空电缆，由一根铝包钢芯导线和多根铝合金导线绞制而成，铝包钢芯导线有较好的抗拉性能，铝合金导线与钢绞线相比，具有较好的导电性能，同时也具有一定的抗拉性能，因此整个电缆既具有较好的抗拉性能，又具有较好的导电性能。
附图说明
图1为本发明的结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图和具体实施例对本发明做进一步说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示的架空电缆，包括一根圆芯线，芯线的中心为钢芯1，钢芯外包覆有铝层2，芯线外绞合有六根圆形铝合金导线3。
当需要较粗的架空电缆时，可以用更多的铝合金导线进行绞合。
铝包钢芯导线有一定的抗拉性能，铝合金导线也具有一定的抗拉性能，因此这种架空电缆具有较好的抗拉性能。而铝合金的比重比钢小，且铝合金的导电性能要好于钢，因此这种架空电缆与相同重量的钢绞线相比，其导电截面有所增加，因此有载流量大、电阻小的优点，其导电性能有了较大提高。
以上所述实施例仅表达了本发明的实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
