POWERCHINA has done power transmission and transformation engineering work on various voltages -- 110 kV, 220 kV, 330 kV, 500 kV, 660 kV, 750 kV, 800 kV, 1,000 kV -- and has the equipment for power transmission and transformation engineering work at various voltages, as well as an international traction machine and tensioner.

By the end of 2014, it had completed work on 13,000 km of power transmission lines at or above 110 kV, and had 8,000 km of lines of 220 kV or higher, 5,000 km of lines at or above 500 kV, and 750 km of 750 kV or higher. It had completed six transformer substations and convertor stations at 750 kV or higher, 70 at 500 kV or higher, and 300 at 220 kV or higher
