Description

复合式电力传输导线
技术领域
本实用新型涉及一种电力导线，尤其涉及一种复合式电力传输导线。
背景技术
目前所使用的导线，都是由一根铜线在中心，其外面包有绝缘层，而对于载流量大的导线，导体是由多股铜线拧绞组合在一起而增加电流的流量。该导线的缺点是：不能发挥最大的单位载面的流量，因为电流都是容易从导体的外表面流过，中心部流量很小，此种导线的结构不仅加大了电阻还浪费了大量的导体用料，而且不符合电流集肤效应的自然法则。
发明内容
本实用新型的目的就在于为了解决上述问题而提供一种复合式电力传输导线。
本实用新型通过以下技术方案来实现上述目的：
本实用新型包括轴向方向相同的钢芯、导体、护套和包覆于所述钢芯上的绝缘层，所述导体呈筒状，所述导体套装于所述绝缘层上，所述护套包覆于所述导体上。
进一步，所述导体为铜导体。
本实用新型的有益效果在于：
本实用新型通过在电力导线的导线中心设有一根提高抗拉强度的钢芯，    该钢芯可根据导线截面的大小、可以由一股或多股钢丝绞合而成；本实用新型具有成本较低低、节约成本、接触面大和导电力强的优点。
附图说明
图1是本实用新型的剖视图。
图中：1—钢芯、2—绝缘层、3—铜导体、4—护套。
具体实施方式
下面结合附图对本实用新型作进一步说明：
如图1所示，本实用新型包括轴向方向相同的钢芯1、铜导体3、护套4和包覆于钢芯1上的绝缘层2，铜导体3呈筒状，铜导体3套装于绝缘层2上，护套4包覆于铜导体3上。
本实用新型通过在电力导线的导线中心设有一根提高抗拉强度的钢芯，    该钢芯可根据导线截面的大小、可以由一股或多股钢丝绞合而成；本实用新型具有成本较低低、节约成本、接触面大和导电力强的优点。
