Optimization of electric transmission line of power grid with carbon fiber composite core conductor

الملخص EN

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.
