SF-180000/500
This product is a step-down transformer used for the self-consumption of electricity in substations or hydropower stations, providing power load for low-voltage equipment or lighting. It is an important component of the station power system. This product is mainly used in ultra-high voltage converter stations, where its function is to step down the voltage from the 500kV grid to 35kV, supplying power to the 35kV station transformers.
