PT PLN (Persero) UITJBT has successfully completed its first ACCC InfoCore® System project in Indonesia, a significant milestone in the region’s power transmission upgrades. The project, named Mojosongo – Banyudono, located in Boyolali, Central Java, involved replacing the existing ACSR Hawk conductor with the advanced ACCC Lisbon Conductor using the ACCC InfoCore® System to confirm and document core integrity.
The project covered a total line length of 10.9 kilometers, spanning two circuits, and utilized 72 kilometers of ACCC® Lisbon size conductor. The new conductor was bundled in both single and twin configurations and is designed to operate at a voltage of 150 kV. The steel lattice towers used in the project supported the conductor, with an average span length of 400 meters and the longest span stretching 466 meters between towers 11-12. The line also crossed a highway, adding to the complexity of the installation process.
This major upgrade was overseen by PT PLN PUSMANPRO’s engineering team, with PT Sangkan Jaya serving as the contractor for the installation. The project was managed by Pak Cepi Indra from PT Sangkan Jaya, supported by a dedicated team of installation professionals from CTC GLOBAL including PT. DINAMIKA ACCC Master Installers Yaniar, Susanto, and Shalahuddin, alongside KAMESA supervisors Ryan, Iqbal, and Rama.
The installation process for the two circuits was carried out in stages: Circuit 2 started on November 4, 2024, and was energized by November 23, 2024, while Circuit 1 began on November 24, 2024, and was energized on December 5, 2024. The new conductor significantly enhances the line’s capacity, providing a more reliable and efficient power transmission solution for the region.
The project utilized tensioners from TEMA, pullers from Tesmec, presses from KUDOS, and clamps from TEMA, with pulling socks provided by Omac. This collaboration between utility operators, engineers, contractors, and suppliers reflects the success of the first commercial InfoCore® Project in Central Java, marking a significant step in the modernization of Indonesia’s electrical grid.
The success of this project sets a strong precedent for the continued adoption of the ACCC InfoCore® Technology in Indonesia and beyond. With the completion of this project, PLN demonstrates its commitment to modernizing and upgrading the country’s electrical infrastructure, ensuring greater stability and efficiency in the delivery of power to its customers.
