导线是架空输电线路的最基本组成元件之一，架线工程投资占工程本体投资30%左右，其对整条架空输电线路的杆塔、基础、绝缘子和金具强度、经济技术指标等起着决定性影响。为将更多的新技术、新材料、新工艺应用到电网建设中，根据国家电网基建要求，在导线的选型过程中从电能损耗和载流量、弧垂、杆塔荷载、风偏角、投资分析和年费用等多个方面对普通钢芯铝绞线和三种节能导线（即高导电率钢芯铝绞线、铝合金芯高导电率铝绞线和中强度全铝合金绞线）进行了详细的技术经济比较，最后结合通用设计杆塔的利用和标准化工作开展等因素，推荐4×JL1/LHA1-465/210铝合金芯高导电率铝绞线。

Conductor is one of the most basic components of overhead transmission lines, wiring engineering investment accounted for about 30% of the body of investment project, and it plays a decisive role in The whole of overhead transmission line tower, foundation, insulators and fittings strength, economic and technical indicators . In order to encourage more and more new technology, materials, process to the power construction, According to the State Grid Power Infrastructure Department (2013) No.99 document “on the strengthening of energy-saving State Grid Corp transmission line wire application work notice" requirements, in the selection process of wire, We made a detailed comparition for ordinary steel core aluminum stranded wire and three kinds of energy wires, such as the power loss, load flow, sag, overload capacity, tower load, wind yaw angle, investment analysis and annual fees. Combined with the use of standard work and carry out general tower design and other factors, we finaly recommendate the 4 * JL1/LHA1-465/210 Aluminum aloy core high conductivity of aluminium stranded wire.
