摘要：With the rapid development of the society, electricity has become a vital part of people's life.
However, due to the limitation of some natural conditions, a series of power accidents often
occur. Therefore, optimization and improvement of power transmission lines has become an
important research topic. In this study, electric transmission line was optimized by using carbon
fiber composite core conductor, and a mathematical model of composite temperature field of
carbon fiber conductor under heavy load environment was established. Compared to the
traditional steel core aluminium conductor, the carbon fiber composite core conductor had lower
surface temperature and better heat resistance and current carrying capacity. Moreover the
experiment of resistance to corrosion was carried out on the two kinds of conductor, and it was
found that the corrosion rate of the carbon fiber composite core conductor was lower than that
of the steel core aluminium conductor under acid rain solution with 3.0 PH value. In
conclusion, the corrosion resistance and thermal properties of the carbon fiber composite core
conductor are good. This study provides a new mode for the optimization and improvement of
electric transmission lines.
