The SZ13 transformer is a high-performance medium-voltage power device engineered to address voltage instability in modern power grids. As a dedicated 10kV~35kV on-load voltage-changing transformer, its primary function is to adjust voltage levels without interrupting power supply— a critical requirement for grids where unstable voltage could disrupt industrial production or residential electricity use. It acts as a "voltage stabilizer" for power systems, ensuring consistent power quality even in areas with frequent voltage fluctuations, making it indispensable for upgrading urban and rural power networks and integrating new energy sources.
Unlike standard transformers, the low-loss transformer design of the SZ13 series prioritizes energy conservation, with loss indicators far below national standards to align with global low-carbon development goals. It integrates advanced components like vacuum on-load tap-changers and fully sealed oil tanks, which not only enhance performance but also reduce maintenance needs. This combination of efficiency, reliability, and adaptability sets it apart from conventional models, especially in scenarios requiring continuous voltage regulation.
Energy Efficient: Using 30Q155 high permeability silicon steel sheet, no-load current <1%, annual energy saving up to 15,000kWh
Intelligent Voltage Regulation: Optional PLC control system, automatically adjusting tap according to voltage deviation, response time <10s
Long Service Life Design: Corrugated oil tank with 20% increased heat dissipation area, hot spot temperature controlled below 95℃, expected service life 30 years
The SZ13 series’ low-loss performance is a standout feature: both no-load loss and load loss are significantly lower than national standards, cutting long-term energy consumption and operational costs for users. This efficiency is achieved through high-permeability silicon steel sheets and optimized winding design, ensuring minimal energy waste during power transmission and voltage regulation.
The fully sealed oil tank design prevents oil leakage and blocks moisture, dust, and other contaminants from entering the transformer. This protection safeguards internal components, extends the device’s service life, and eliminates the need for frequent oil-related maintenance. The sealed structure also enhances reliability in harsh outdoor or industrial environments, where exposure to external elements could compromise performance.
Equipped with an optional PLC control system, the SZ13 series realizes intelligent voltage regulation by automatically adjusting taps based on real-time voltage deviations. This fast-response system ensures that voltage fluctuations are corrected promptly, maintaining stable output for connected equipment. The integration of smart technology reduces manual intervention, making the transformer ideal for large-scale power grids requiring continuous monitoring and adjustment.
The corrugated oil tank design increases the heat dissipation area by a significant margin, effectively controlling hot spot temperatures within safe limits. This thermal management system ensures the transformer operates at optimal working status even under high-load conditions, preventing overheating and further enhancing durability.
The SZ13 transformer features a rated voltage range of 10kV to 35kV, compatible with most medium-voltage power grids used in urban, rural, and industrial areas. Its rated capacity range is designed to accommodate diverse load demands, from small-scale industrial workshops to large power grid hubs, ensuring flexibility across applications.
A key parameter is the voltage regulation range, which allows precise adjustments to counteract voltage fluctuations and maintain stable output. The vacuum on-load tap-changer (standard or optional) enables smooth voltage adjustment under full load, while the transformer’s passage of short-circuit tests confirms its ability to withstand electrical faults without damage.
Cooling relies on the corrugated oil tank with oil as the cooling medium, ensuring efficient heat dissipation and safe operating temperatures. Additionally, the no-load current is minimized to further enhance energy efficiency, reinforcing the series’ low-loss advantage. All parameters comply with industry safety and performance standards, ensuring reliable integration into existing power systems.
The SZ13 transformer is widely used in urban and rural power grids, regulating voltage to ensure stable electricity supply for homes, shops, and small-to-medium enterprises. It plays a key role in grid modernization projects, addressing voltage fluctuations caused by varying load demands and aging infrastructure.
In industrial enterprises— especially those with heavy machinery or precision equipment— the transformer prevents production disruptions caused by voltage instability. Its ability to adjust voltage without power interruptions is critical for continuous-production industries, where even brief outages can result in significant losses.
As a new energy grid-connected transformer, it is ideal for wind power and photovoltaic (PV) system connection. It stabilizes the variable output of renewable energy sources before feeding power into the main grid, ensuring compatibility with grid quality standards and reducing energy waste during transmission.
The SZ13 series is a core device in hub substations of power systems, acting as a central node for voltage regulation. It enables efficient power distribution across large regions, balancing supply and demand to maintain grid stability and reliability.
The SZ13 low-loss transformer achieves low loss through high-permeability silicon steel sheets and optimized winding design, with both no-load and load losses below national standards.
