Abstract

一种铝包钢线外绞合扇形铝线的抗冰雪架空电线，具有由铝包钢线绞合成的线芯，在线芯外绞合扇形铝线。本实用新型由于具有由铝包钢线绞合成的线芯，提高了输电线的抗拉强度，架设时输电线的跨距能够增大，架设同样距离的架空输电线可以少用架设杆塔，节约成本，少占土地；由于在线芯外绞合扇形铝线，线与线之间的间隙小，增加有效截面积，线的外径可以减小，适应大跨距架设，而且外层的扇形铝线使线的外表形成一个完整的圆，表面紧密光滑，不易积冰雪。

Description

铝包钢线外绞合扇形铝线的抗冰雪架空电线
技术领域
本实用新型涉及一种输电线，尤其是超高强度、大跨距、抗冰雪架空电线。
背景技术
现有架空电线一般由镀锌钢线构成的线芯外绞合圆形铝线组成。这种架空电线一是抗拉强度不够高，架设时电线的跨距较小，架设同样距离的架空输电线需多用架设杆塔，导致成本增加，多占土地；二是线芯外全部用圆铝线绞合导致线与线之间的间隙大，有效截面积小；三是线的外表面凹凸不平，易积冰雪，增加线的负重，容易造成损坏。
发明内容
为了克服现有架空电线的不足，本实用新型提供一种铝包钢线外绞合扇形铝线的抗冰雪架空电线。
本实用新型提供的一种铝包钢线外绞合扇形铝线的抗冰雪架空电线，具有由铝包钢线绞合成的线芯，在线芯外绞合扇形铝线。
本实用新型的有益效果是：由于具有由铝包钢线绞合成的线芯，提高了输电线的抗拉强度，架设时输电线的跨距能够增大，架设同样距离的架空输电线可以少用架设杆塔，节约成本，少占土地；由于在线芯外绞合扇形铝线，线与线之间的间隙小，增加有效截面积，线的外径可以减小，适应大跨距架设，而且外层的扇形铝线使线的外表形成一个完整的圆，表面紧密光滑，不易积冰雪。
附图说明
图1是本实用新型的横截面示意图。
在图1中，1、扇形铝线，2、铝包钢线。
具体实施方式
参照图1，在将数根铝包钢线2绞合成线芯，再在线芯外绞合扇形铝线1，即制成本实用新型。
