Abstract

本实用新型公开了一种导线，特别是一种用于避雷及接地的导线，其特征在于：所述的导线由钢芯线[1]和包覆在钢芯线[1]外侧的铜层[2]构成。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芯线成本低的优点，钢芯线的强度高，也解决了易被破坏和丢失等问题，克服了现有技术的不足。

Description

用于避雷及接地的导线
技术领域：
本实用新型涉及一种导线，特别是一种用于避雷及接地的导线。
背景技术：
目前，在建筑物或其他设施中，不可避免地安装避雷及接地设施，该设施中所使用的避雷导线和接地导线均为铜合金线，价格高，导线强度低，易被破坏和丢失。
发明内容：
本实用新型的目的是提供一种成本低、强度高的避雷及接地的导线，克服现有技术的不足。
本实用新型的技术解决方案是：一种用于避雷及接地的导线，其特征在于：所述的导线由钢芯线1和包覆在钢芯线1外侧的铜层2构成。
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芯线成本低的优点，钢芯线的强度高，也解决了易被破坏和丢失等问题，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。
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。
