The grayish-white equipment standing on the sand is the core of the outdoor substation - the oil-immersed transformer. The high-voltage busbar structure above its head extends far into the distance, and two operation and maintenance personnel beside it are checking the parameters. In this dry and open environment, it bears the heavy responsibility of being the "voltage regulation hub" for regional power.
Unlike indoor equipment, this outdoor transformer comes with a sand-proof seal and high-temperature resistant heat dissipation design: the shell gaps are sealed to prevent dust, and the oil conservator can adapt to oil level fluctuations under diurnal temperature differences. Even with strong sunlight in the desert, it can stably convert the high voltage from the transmission line to medium and low voltage suitable for surrounding industrial and mining areas and villages.
The daily inspection conducted by operation and maintenance personnel ensures its "healthy operation": from the oil level scale to the temperature of the wiring terminals, every data point is related to the stability of regional power supply. At the transmission nodes far away from the city, this transformer acts like a "power heart" that can withstand wind and sand, steadily pumping energy from the distant power grid into the production and life of this land.
