35kV Class SZ20 Series Dual Winding On-load Voltage Regulating Transformer (Level 2 Energy Efficiency)

This product is equipped with advanced on-load voltage regulation functionality, capable of dynamically adjusting the output voltage in real-time based on load current variations, ensuring continuous stability of the supply voltage. It is highly suitable for application scenarios with stringent requirements for power stability, such as industrial production and telecommunication systems. In terms of material selection and manufacturing processes for core components, the core is made of high-permeability grain-oriented cold-rolled silicon steel sheets, utilizing a 45-degree fully mitered joint process, which effectively reduces no-load current and no-load losses, improving energy efficiency. The conductors are made of high-tensile-strength paper-insulated or enameled copper wire, ensuring reliable electrical connections. The windings are constructed in a layer or disc structure, providing the product with strong short-circuit resistance, further enhancing operational stability and safety.
