Abstract

The modern overhead lines with High Capacity Low Sag (HCLS) conductors can be operated at higher current carrying capacity. The main advantage of HCLS conductors is the special design of operating conditions, which cause the transformation of the mechanical pull load from the conductors to the reinforcing core. This transformation is called "knee point temperature". This study aims to determine the knee point temperature and the effect on sag HCLS conductors. The simulation will be conducted on the HCLS conductors, namely ACCC/TW LISBON (310), which stretches between a span of 100meters. The electrical loading of conductors is gradually giving until a temperature of 180oC is reached. From the simulation results, we can determine the knee point temperature of the ACCC/TW LISBON (310) conductor is around 60-62oC. The value of the sag after the knee point temperature tends to be stable even though the ampacity loading is increased.
