There is a good job in electrical engineering and automation, generally working in electric power bureau (power supply company), EHV, power plant, electric power design unit and so on. Transmission lines generally work at ultra-high voltage, so there is no problem in employment, but there will be some strength, that is, they often climb telephone poles. Transmission line engineering technology must be based on engineering technology, that is, doing engineering, that is, practicing more. Theoretical research on transmission lines focuses on theoretical research. If you don't know, you can go to official website of China Three Gorges University to know, or you can find the telephone consultation inside.
