HCLS Special Hot Yoke for Live Line Maintenance

Abstract

At present, the demand for electricity on the island of Sumatra is proliferating. This need encourages electric power providers to make efforts to increase the capacity of electricity distribution. One of the most efficient ways to improve the distribution power is by reconducting existing transmission lines. Reconducting did by replacing ACSR conductors as HCLS conductors. This High Capacity Low Sag (HCLS) conductor technology has different maintenance treatments compared to ACSR, especially in tension isolator replacement work. Initially, we had to carry out maintenance with an off-line condition, but after we made these new, tested equipment, we were able to do the work without causing the transmission line to off-line again. This paper will explain how we do it.
