由于导线是电力线设计的主要成本组成部分之一，因此必须选择最合适的导线类型和尺寸，以获得最佳的运行效率。在选择导体时应采取系统的方法。在此过程中必须考虑诸如张力负载、冰和风负载、线路的电流负载、电压稳定性、环境影响、电损耗、环境条件以及许多其他因素。目标是选择一种能够以最低的应用成本体现最佳电导率重量比和/或强度重量比的导体。导体的电气和机械性能、热性能以及应力-应变关系将决定给定设计的导体类型和尺寸的选择。本文的目的是为输电和配电工程师和规划人员提供有关各种导线设计的基本信息。<<ETX>>
Since the conductor is one of the major cost components of a power line design, it is essential that the most appropriate conductor type and size be selected for optimum operating efficiency. A systematic approach should be taken in the selection of the conductor. Factors such as tension loads, ice and wind loads, current loading of the line, voltage stability, environmental effects, electrical losses, ambient conditions, and many others must be considered in the process. The goal is to select a conductor that exemplifies the best conductivity-to-weight ratio and/or strength-to-weight ratio at a minimal cost for the application. The electrical and mechanical properties, thermal properties, and stress-strain relationship of the conductor will dictate the choice of conductor type and size for a given design. It is the purpose of this paper to provide basic information concerning various conductor designs available to transmission and distribution engineers and planners.<<ETX>>
