All the ACSR Conductor Questions & Answers below include a hint and a link to the relevant topic wherever possible. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of the ACSR Conductor. Aluminium Conductor Steel Reinforced is a type of overhead power transmission cable that is widely used in electrical power distribution and transmission networks. It is composed of a central core of steel wires surrounded by one or more layers of aluminium wires. The steel core provides mechanical strength to the conductor, while the aluminium outer layers provide high conductivity and low weight. ACSR conductors can carry high voltages over long distances with low power losses, making them ideal for high-voltage transmission lines. ACSR conductors are available in various sizes and designs, with different combinations of aluminum and steel wires. The design of the conductor is chosen based on the specific application, including the voltage level, distance, and environmental conditions. Overall, ACSR conductors are a reliable and cost-effective option for power transmission and distribution, and they are commonly used worldwide. 1). What is the standard form of SAC?
