Fans are key components for heat dissipation, ventilation, cooling, dust removal, and dehumidification in electrical equipment. Transformers, high and low voltage switchgear, frequency converters, energy storage converters, charging piles, and other electrical equipment continuously generate heat during operation. Axial and centrifugal fans provide forced convection cooling to prevent high-temperature aging and short-circuit failures of components. Fans in generator sets and distribution cabinets expel humid air and dust from inside the equipment, improving the internal operating environment. Energy-saving variable frequency fans can intelligently adjust airflow based on equipment temperature, are low-noise, durable, and consume less energy, ensuring the long-term stable and safe operation of electrical equipment. They are widely used in power plants, substations, energy storage power stations, and new energy charging stations.
