| 摘 要： | 间隙型增容导线是耐热铝合金导线的一种。它的高强度钢芯和合金铝股之间的特殊结构，使其耐受运行温度高达210℃。它的载流比常规同截面的钢芯铝绞线高几乎两倍，弧垂也较小。通过110kV步畔线更换间隙型增容导线工程的案例分析，它的实践应用经验可为同类案例的处理提供借鉴参考。

| Abstract: | Gap Type Up-Rating Conductor is a kind of heat resisting aluminum alloy conductor. With special structure between high strength steel core and aluminum alloy strands, its operating temperature is up to 210 ℃, results lower sag and almost two times of current carrying of the conventional ACSR of same cross-section. Through a practical application example, the structure, characteristic and engineering detail of this conductor is introduced and the proper opinion to further application is put forward. |
