Medium- and high-voltage electrical equipment are widely used in Power Systems and mainly include high-voltage circuit breakers, transformers, instrument transformers, and insulators. High-voltage circuit breakers are used to control and protect power lines, enabling rapid interruption of fault currents. Transformers are responsible for stepping up or stepping down voltage levels to improve transmission efficiency. Instrument transformers are commonly used for measurement and protection to ensure the Safe Operation of the system. Insulators support conductors while maintaining insulation, effectively preventing short circuits.

In industrial applications, these devices play key roles not only in power generation and distribution but also in crucial sectors such as wind power, electrical grids, and substations. By selecting and applying these medium- and high-voltage devices appropriately, the overall safety and stability of the power grid can be effectively enhanced.
