In high-energy-consuming industries such as steel, petrochemicals, and mining, the startup of high-power motors has always been a critical challenge—characterized by significant inrush currents, severe voltage drops in the power grid, and a high risk of mechanical damage. These issues not only affect production efficiency but also pose serious threats to equipment safety. Recently, Changsha ATA's independently developed ATAF-H10/18000 medium- and high-voltage soft-starter device for energy-saving applications was successfully deployed in a large-scale air separation and gas supply project at a major steel enterprise. With its outstanding performance, the device achieved three major breakthroughs: "smooth startup, stable grid operation, and robust mechanical protection," setting a new industry benchmark.
