Description

Technical field [0001] The invention belongs to the field of power transmission and distribution line equipment, and relates to an aluminum alloy component for power transmission and transformation of power lines and a preparation method thereof. Background technique [0002] Components for power line transmission and transformation are widely used in low-voltage, medium-voltage, and high-voltage transmission lines, as well as municipal and transportation lines. The traditional power line transmission and transformation components are made of iron materials, and the surface is hot-dip galvanized. The iron material has a large proportion and is inconvenient for transportation and installation; and the surface is easy to oxidize, and the surface must be treated by pickling and hot-dip galvanizing. Therefore, the process is complicated, the production cost is high, and the process pollutes the environment seriously. It is of great significance to use materials with small specific g...
