That's not the case. The number of volts of electricity generated by the generator is determined based on many factors such as unit capacity, transmission distance, grid transmission level, etc. The 12V you are talking about is the kind of small connected battery that can be inverted into alternating current for use. Generators generally have a power of only a few kilowatts, but the single-machine capacity of large-scale wind turbines can reach the megawatt level. The electricity generated is definitely not 12V, but should be at the level of 10,000 volts. Otherwise, how thick should the cable be? It's simply impossible. We know that the product of voltage and current is capacity, so the higher the voltage, the smaller the current, and the higher the voltage, the smaller the power transmission loss. The electricity generated by the generator is generally boosted by a step-up transformer and then connected to the power grid.
There are nine main brands of Yuchai generator sets circulating in the domestic market. They are: Weichai, Shangchai, Yuchai, Jichai, Wudong, Cummins, Daewoo and Volvo; among which Cummins is The Sino-US joint venture brands are Dongfeng Cummins and Chongqing Cummins respectively. Daewoo (South Korea) and Volvo (Sweden) are imported brands, and the remaining five brands are purely domestic.
