Aluminium Conductor Steel Reinforced , Overhead Bare Wire

Generally, there is one aerial bare wire for each phase. For 220kV and above lines, phase splitting wire is adopted in order to reduce corona loss and corona interference due to large transmission capacity, that is, two or more wires are used for each phase. Adopting split wire can transmit large electric energy, and the electric energy loss is less, and it has better anti-vibration performance. Conductors are often subjected to various natural conditions in operation, and must have good conductivity, high mechanical strength, light weight, low price, strong corrosion resistance and other characteristics. Because China's aluminum resources are richer than copper, and the price difference between aluminum and copper is large, so almost all steel core aluminum stranded wire. Each conductor shall have only one connector in each distance. Conductors and lightning conductors shall not have connectors in crossing highways, rivers, railways, important buildings, power lines and communication lines.
