AAC, ACSR form part of the family of Overhead Conductors, Transmission Conductors, and Power Distribution Conductors. These cables are formally known as All Aluminium Conductor (AAC) and Aluminium Conductor Steel Reinforced (ACSR). These overhead aluminum conductors are used as power transmission and distribution lines. All aluminum conductors are made up of one or more strands of aluminum wire depending on the specific application.
AAC are a refined Aluminium stranded conductor with a minimum metal purity of 99.7%. It is principally used in urban areas where spacing is short and the supports are close. It can be used in coastal regions owing to its high degree of corrosion resistance and is also used extensively within the Railway and Metro industries.
ACSR are available in a range of steel contents ranging from 6% to 40% for additional strength. The higher strength ACSR conductors are commonly used for river crossings, overhead earth wires, and installations involving extra-long spans. The ACSR conductor can, against any given resistance, be manufactured to different tensile strengths, so a high tensile strength combined with its lightweight properties means it can cover longer distances with fewer supports. Due to the greater diameter of the ACSR conductor, a much higher corona limit can be obtained which is advantageous on high and extra-high voltage overhead lines.
