The use of Aluminum Conductor Composite Core Steel (ACCCS) in the electrical distribution system at PT PLN ULP Sinabang has been proven to improve system reliability compared to the previously used Aluminum Alloy Conductor (AAAC). This study compares the performance of both conductors using reliability indicators such as SAIDI (System Average Interruption Duration Index) and SAIFI (System Average Interruption Frequency Index). The results show that ACCCS offers superior resistance to extreme temperatures, corrosion, and wind loads, which significantly reduces the frequency and duration of power outages. After replacing AAAC with ACCCS on a 17.4 km network consisting of 11 transformers, the voltage at the transformer increased from 210 V to 223 V under a 17 A load. Additionally, the SAIDI index improved from 9.0 to 0.56 hours/year, and the SAIFI index decreased from 10.9 to 2.39 interruptions/year. These findings highlight the effectiveness of ACCCS in enhancing the reliability and efficiency of power distribution systems, particularly in regions with challenging environmental conditions
