New energy field

Transformers are the core equipment for the efficient operation of new energy systems. Their role runs through the entire chain of power generation, power transmission, energy storage, and terminal adaptation. The core functions focus on voltage adaptation, system coordination, and safety assurance.

Industrial automation field

Increase (step - up) or decrease (step - down) the voltage of the input power supply to meet the voltage requirements of different electrical equipment; at the same time, it can achieve electrical isolation, cut off the direct electrical connection between the primary and secondary sides, and improve the safety of electricity use.

Medical field

The core value of transformers in the medical industry lies in voltage conversion and electrical isolation, providing safe and stable power support for various medical devices. Through precise voltage transformation and isolation of clutter, transformers become the "safety hub" of the medical power system.

Consumer electronics field

Transformers are the core components of electrical appliances. They are used for voltage transformation and electrical isolation, providing suitable operating voltages for different functional modules inside the equipment to ensure the stable operation of the equipment and electrical safety.
