Sag‐tension evaluation of high‐temperature gap‐type conductor in operation

Abstract Low‐sag conductors are characterised by their ability to operate above the “knee‐point temperature” (KPT). Sag‐tension performance must be calculated while designing a new overhead line. The ampacity limit of the conductor is influenced by the sag and the temperature of the conductor. The m...
