摘　　要：耐热导线是增容导线的一种类型,其和钢芯铝绞线的重量、外径等结构与参数是一致的,但是流量参数不同。在增容改造过程中耐热导线应用的较为普遍。本文主要对耐热导线的迁移点温度及弧垂计算方法展开研究,旨在增强耐热导线的应用效果与价值。Heat-resistant wire is a type of capacity-increasing wire.Its structure and parameters such as the weight and outer diameter of the steel core alμminμm stranded wire are the same,but the flow parameters are different.Heat-resistant wires are more commonly used in the process of capacity expansion and transformation.This paper mainly studies the calculation method of migration point temperature and sag of heat-resistant wire,aiming to enhance the application effect and value of heat-resistant wire.
