ABC systems are used in city power grid transmission lines, with an operating voltage of up to 600/1000 volts. They are mainly used for overhead single-phase and three-phase electricity distribution, as well as other purposes. They have a stable working temperature range of -10°C to 80°C and are economical, with good electrical properties and a lower cost than copper cables. They are also flexible and easy to install, making them suitable for distribution and other applications. They provide safety by preventing electric short circuits and potential fire risks, while being durable against UV radiation, moisture, and corrosion. Additionally, they have an aesthetically pleasing finish and are adaptable to the physical properties and electrical needs of the African environment and market.
