Description

一种低成本电线
技术领域
本实用新型涉及一种电线， 具体涉及一种降低成本结构型电线。 背景技术
目前， 电力、 电信系统普遍使用的电线、 电缆导体材料多为铜或铝， 由于金属铜、 铝的 价格较为昂贵， 使得优质电线的成本非常高昂。 随着世界有色金属用量的不断增长和矿产资 源的日益缺乏， 导致铜、 铝的价格飞速上涨， 电线市场上出现了直径不合要求、 截面积不达 标的产品， 以及使用杂铜、 铝的伪劣产品。 虽然有人曾提出使用廉价金属来代替铜、 铝， 但 这种单纯的替换会影响电线的使用性能， 效果很不理想。 实用新型内容
本实用新型针对现有技术的不足， 提出了一种通过在铁线外设置铜或铝镀层， 具有节约 电线的材料成本， 且不影响电线导电效率的降低成本结构型电线。
本实用新型的技术方案如下：
降低成本结构型电线， 其特征在于： 它包括一铁线内芯， 以及在所述铁线外设置的镀层， 所述镀层为铜或铝， 所述镀层的厚度是电线总直径的 5%〜12. 5%。 可根据实际需要选择相应 的镀层厚度。
所述铁线的材料为纯铁或含锰的铁线或含硅的铁线或铁磁物质。
所述镀层外设置保护层， 所述保护层为烤漆或塑料薄膜。
所述镀层为电镀或镏形成的， 优选先进工艺制备。
本实用新型的技术效果如下：
本实用新型由于在铁线外面设置材料为铜、 铝的镀层， 在不影响电线的导电效率的前提 下， 如果镀层的厚度是电线总直径的 5%〜12. 5%， 则可节省约 70%左右的铜或铝， 由于铜价是 铁价的十几倍， 铝价是铁价的 9倍， 电线总成本可大幅下降， 产生可观经济效益， 也有利于 节约资源和环境保护。 由于铜、 铝等金属材料的熔点低于铁线， 因而可以轻易地镀在铁线的 外表面， 工艺简单， 易于实现。 同时由于铁线的强度较高， 因而可提高电线整体的强度， 延 长电线的使用寿命。
含锰的铁线可使拉力更强， 而铁线为铁磁物质， 对电线表面自由电子的逃逸有所钳制， 附图说明
图 1是本实用新型横截面结构示意图
图 2是本实用新型纵截面结构示意图
具体实施方式
下面结合附图对本实用新型进行说明。
如图 1、 图 2所示， 本实用新型在粗细不等的铁线 1表面设置有镀层 2， 镀层 2为铜或 铝， 铁线 1的材料为纯铁， 或含锰或含硅的铁线， 所述镀层可以是电镀或镏形成的。 其中镀 层 2的厚度是电线总直径的 5%〜12.5%， 镀层 2的厚度可优选为电线总直径的 7.5%〜10%。 并可根据需要在镀层 2之外， 可根据需要设置保护层， 保护层可为烤漆或塑料薄膜等。
当交变电流通过本实用新型的电线时， 交流电在电线内部产生 "趋肤效应"， 使得愈近 电线表面电流密度越大。 电压越高， 电流密度越大， "趋肤效应"越显著。 当电压很高的电流 通过导线时， 电流只在导线很薄的表面环层流过， 导线的中心部分几乎没有电流通过， 因而 可以把这中心部分用铁线 1代替， 并不影响电线的导电效率。
虽然趋肤效应对直流电的作用不如对交流电的作用强， 但电线中铁线 1也是导体， 且铁 线 1的导电率低于铜或铝， 在电线中电子会本能地选择导电率高的通道流动， 所以本实用新 型的电线也可应用于直流电路中。
应当指出， 以上所述具体实施方式可以使本领域的技术人员更全面地理解本实用新型创 造， 但不以任何方式限制本实用新型创造。 因此， 尽管本说明书参照附图和实施例对本实用 新型创造已进行了详细的说明， 但是， 本领域技术人员应当理解， 仍然可以对本实用新型创 造进行修改或者等同替换， 总之， 一切不脱离本实用新型创造的精神和范围的技术方案及其 改进， 其均应涵盖在本实用新型创造专利的保护范围当中。
