Abstract

一种超高强度镀锌钢线外绞合扇形铝合金线的架空电线，具有由超高强度镀锌钢线绞合成的线芯，在线芯外依次绞合扇形铝合金线和圆形铝合金线。本实用新型由于具有由超高强度镀锌钢线绞合成的线芯，提高了电线的抗拉强度，架设时电线的跨距能够增大，架设同样距离的架空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合金线，线与线之间的间隙小，增加有效截面积，线的外径可以减小，也适应大跨距架设。

Description

超高强度镀锌钢线外绞合扇形铝合金线的架空电线
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合金线组成。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合金线绞合而成，导致线与线之间的间隙大，有效截面积小、线的外径大。
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超高强度镀锌钢线外绞合扇形铝合金线的架空电线。
本实用新型提供的一种超高强度镀锌钢线外绞合扇形铝合金线的架空电线，具有由超高强度镀锌钢线绞合成的线芯，在线芯外依次绞合扇形铝合金线和圆形铝合金线。
本实用新型的有益效果是：由于具有由超高强度镀锌钢线绞合成的线芯，提高了电线的抗拉强度，架设时电线的跨距能够增大，架设同样距离的架空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合金线，线与线之间的间隙小，增加有效截面积，线的外径可以减小，也适应大跨距架设。
附图说明
图1是本实用新型的横截面示意图。
在图1中，1、圆形铝合金线，2、扇形铝合金线，3、超高强度镀锌钢线。
具体实施方式
参照图1，将数根超高强度镀锌钢线3绞合成线芯，再在线芯外依次绞合扇形铝合金线2、圆形铝合金线1，即制成本实用新型。
