Abstract

本实用新型公开了一种导线，特别是一种它是由多股单元导线构成的绞线，其特征在于：所述的单元导线由内部的钢芯线[1]和位于钢芯线[1]外侧的铜层[2]组成的。由于导线是由两种金属材料组合而成的铜包钢导线，其内的钢芯线1具有强度高、成本低的优点，钢芯线1外表的铜层2具有导电性好的优点，本实用新型结合了铜的优良导电性和钢的强度高、成本低的优点，绞线内部也省去了加强钢丝，简化了加工工艺，克服了现有技术的不足。

Description

超高压大跨度电力传输导线
技术领域：
本实用新型涉及一种导线，特别是一种超高压大跨度电力传输导线。
背景技术：
如图2：目前，在超高压大跨度的电力传输中所使用的导线是铝绞线，即多股铝线3绞合成导线整体，由于铝线3的强度较低，所以在绞线的内侧设有一根钢线4用于增加其强度，铝导体虽然有密度小、重量轻、成本低的优点，但它的导电率低，导电性能、焊接性能差，表面易氧化，同时接触电阻大，特别是内侧有用于加强的钢线4，导致加工工艺复杂，提高了生产成本。
发明内容：
本实用新型的目的是提供一种加工工艺简单、导电性好、产品结构简单的超高压大跨度电力传输导线，克服现有技术的不足。
本实用新型的技术解决方案是：一种超高压大跨度电力传输导线，它是由多股导线构成的绞线，其特征在于：所述的导线由内部的钢芯线1和位于钢芯线1外侧的铜层2组成的。
本实用新型与现有技术相比，由于导线是由两种金属材料组合而成的铜包钢导线，其内的钢芯线1具有强度高、成本低的优点，钢芯线1外表的铜层2具有导电性好的优点，本实用新型结合了铜的优良导电性和钢的强度高、成本低的优点，绞线内部也省去了加强钢丝，简化了加工工艺，克服了现有技术的不足。
附图说明：
图1是本实用新型具体实施方式的断面示意图；
图2现有技术中的断面示意图。
具体实施方式：
如图1所示：1为钢芯线，2为铜层，即导线是由内部的钢芯线1和钢芯线1外侧的铜层2复合构成的。在加工制作时可选用金属包覆焊接设备进行拉伸成形，即在钢芯线1的外表用铜带缠绕包覆焊接并拉伸，使铜与钢冶金结合，形成铜包钢线。再利用导线绞合工艺将多股铜包钢导线绞合成绞线。为了达到最佳导电效果和最低成本，导线的导电率可控制在40％左右，铜层2的厚度可决定导线的导电率，因此在包覆焊接加工时根据所需的导电率来确定铜层原厚度。
