AJO (Adjustable Camelong) Conductor Clamp Tool for Repairing Corroded Insulator and String Set Insulators in Transmission Networks and Substations

Transmission and Load Dispatch Center Of Sumatera (UIP3BS) are the units that handle the distribution section of the electricity sector. Electric power is channeled through Transmission and Substations spread across Sumatera Island. The total number of transmissions managed is 28,360 Towers with a total of 208 GI/GITET spread across the Sumatera Island managed by 9 Transmission Implementing Units, 3 Load Control Implementing Units and 1 Sumatera Control Center Unit. Installation growth in Sumatera P3B Main Unit continues to grow with many Transmission and Substation construction projects ongoing. The role of P3B Main Unit is essential to maintain the reliability of installations. For this reason, it is necessary to undergo the maintenance and repair of assets managed by UIP3B Sumatera effectively. Based on field data, there are still many dirty insulators, flash over, and corrosion on insulator string sets that must be repaired immediately. A problem was found when PDKB UPT Padang TEAM carried out maintenance; one of Camelong’s work equipment could not be used on conductors measuring 800 mm2, 1000 mm2, 1200 mm2 and conductors of the HCLS, ACCC, AAAC types. To solve this problem, UPT Padang conducted problem identification and problem-solving analysis by creating an innovation tool. The innovation is AJO (Adjustable Camelong), an equipment for clamping conductors in replacing insulators and string set insulators at transmission and substations. AJO can be used on all sizes of conductors and conductors of the HCLS, ACCC, AAAC types. It can also be used in Live Line and Offline maintenance method.
