Part of the utility’s strategy for meeting load growth is to rely on high-temperature low-sag (HTLS) conductors to increase ratings. CNP tested and approved the use of aluminum conductor, steel supported (ACSS) at 345 kV in ...
WebDec 1, 2024 · Therefore, conductors reinforced with high steel content are less predisposed to high-temperature creep compared to low steel content conductors [35]. Sag-tension models must include high temperature creep when the operating conductor temperature exceeds 75 °C in case of AAC and 100 °C for ACSR conductors. WebFeb 22, 2024 · High-Capacity, Low-Sag ACCC conductors outperform other High-Temperature rated conductors. Though ACSR (Aluminum Conductor Steel Reinforced) conductor is the most widely used conductor, worldwide, the need for a greater capacity conductor was realized in the late 1970’s. The introduction of ACSS (Aluminum Conductor …
