Wire is used to conduct current, energy delivery element. Overhead bare wire is generally one for each phase, 220kV transmission capacity over the line because of the large overhead wires, and in order to reduce the loss of Corona and Corona interference and the use of split and phase conductors per phase using two or more wires. Using split wire can transport larger overhead conductors of electricity prices, and the power loss less overhead wires selection, better anti-vibration properties. Test wires overhead wires running frequently quoted by various natural conditions, must have good conductivity properties, high mechanical strength, light weight, low price, corrosion resistance and other characteristics. Because of China's aluminum rich resources than copper, combined with aluminum and copper prices vary greatly, so almost all the raw material the use of ACSR wire strand 1. provisions shall YB / T699-1999 quality carbon structural steel . Grade 45 # or 50 # steel. 2. galvanized steel with zinc should be used in the GB / T470 number 0 or 1 zinc. Factory Factory Inspection and Testing Methods full inspection and sampling points. According to the requirements of each plate strand appearance, structure, diameter, zinc coating quality, twist method and quality inspection twist full inspection, sampling products on-demand interception sample, according to the requirements of the mechanical properties during sampling and zinc coating weight detection. 1. strand surface quality by visual inspection. 2. strand diameter is 0.1mm indexing should be measured gage measurements. 3. strand breaking tensile testing according to test method GB / T8358-1987 were prescribed.
