Several matte processing methods for aluminum surface are compared and analyzed.The sandblasting process is the simplest and most practicable method which corresponds with the characteristic of continuous production of the wire and cable industries.The diffuse reflectivity of the ACSR outer surface after sandblasting processing is measured.The electrical properties,mechanical properties and aluminum loss situation of aluminum wires of the ACSR before and after sandblasting processing are compared and analyzed.Test shows the performance requirements of the matte overhead conductors produced by using sandblasting processing are satisfied with the engineering needs.
