35kV Class SZ18 Series Dual Winding On-load Voltage Regulating Transformer (Level 3 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. The core is made of high-permeability grain-oriented cold-rolled silicon steel sheets, utilizing a 45° fully mitered joint process, which results in low no-load current and reduced no-load losses. The conductors are made of high-tensile-strength paper-insulated or enameled copper wire. The windings are constructed in a layer or disc structure, providing strong short-circuit resistance. With a capacity range of 30 to 63,000kVA, it is suitable for a wide range of applications.
