Reconstruction of SUTT 150 kV Rancaekek Section 3

Abstract

As the need for electricity in West Java increases, maintenance and capacity enhancement of the transmission network becomes crucial to ensure the continuity and reliability of energy supply. One of the efforts made is the 150 kV Rancaekek–Sunyaragi Section 3 High Voltage Overhead Line (SUTT) reconductoring project. This activity aims to understand the technical process of reconductoring, from the planning stage, implementation, to final testing, and to identify challenges in the field. The methods used include studying technical documents, direct observation, interviews with field technicians, and comparative analysis between existing and new conductors. The results of the observation show that reconductoring is carried out by replacing the old ACSR type conductor with a new, higher capacity conductor such as AAAC or HTLS, without changing the existing tower structure. The process is carried out in stages with stringing and tensioning methods that are strictly controlled to maintain operational safety. The conclusion of this activity states that the reconductoring of SUTT 150 kV Rancaekek–Sunyaragi Section 3 is able to increase the current carrying capacity without the need for new network construction, and is an efficient solution in strengthening the transmission system. This project also provides direct learning for students in the field of electricity and energy project management.
