Compact and Flexible Combined Transformer

Overview: The ZG(F)S Series Compact and Flexible Combined Transformer, also known as the American-style Box Transformer, is a prefabricated substation that integrates the transformer body, high-voltage load switch, and protective fuses within a compact, fully insulated, and sealed structure. This transformer is designed to meet the demands of modern power distribution with its space-saving design, ease of installation, and high reliability .

Key Specifications and Features:

1. Integration and Compact Design:

   • The transformer integrates critical components such as the transformer body, high-voltage load switch, and protective fuses within a single oil tank, reducing the overall size to approximately 1/3 to 1/5 of that of traditional European-style transformers .
   • The split box structure helps avoid oil contamination in the Transformer oil tank, ensuring cleaner and more reliable operations .

2. Safety and Reliability:

   • Fully insulated and sealed construction eliminates the need for insulating distances, providing a safe operating environment and protecting against electrical hazards .
   • The high-voltage side features dual fuse weight range protection, significantly reducing operational costs .

3. Versatility in Power Distribution:

   • Suitable for 10KV ring network power supply, dual power supply, or terminal power supply systems, serving as a transformer, metering, compensation control, and protection device .
   • The product can be used for both ring networks and terminals, with the ability to urgently plug and unplug the cable head when the load current is 200A .

4. Construction and Materials:

   • The tank houses the core and windings and is filled with insulating oil, which serves as both a coolant and an insulator, dissipating heat generated during operation .
   • The core is made of high-permeability silicon steel laminations, providing a low reluctance path for the magnetic flux and reducing core losses .
   • Windings are made of copper or aluminum conductors, with the primary winding connected to the high-voltage distribution line and the secondary winding to the low-voltage distribution circuit .

5. Cooling System:

   • The transformer can be equipped with various cooling systems, including natural air cooling, oil cooling, or forced air/oil cooling systems, depending on the design and operational requirements .

6. Applications:

   • Widely used in residential areas, commercial establishments, industrial plants, and other sectors where reliable and consistent power supply is required .

7. Environmental and Installation Conditions:

   • Suitable for altitudes not exceeding 1000 meters and environmental temperatures ranging from -35°C to +40°C .
   • The installation location should be free from fire, explosion hazards, chemical corrosive gases, and well-ventilated .

8. Technical Standards:

   • The product meets the standards of GB/T17467-1998 "High voltage and low voltage prefabricated substations" and DL/T137-93 Technical Conditions for Ordering 6-35KV Box Substation .

Conclusion: The ZG(F)S Series Combined Transformer is a robust solution for modern power distribution needs, offering a compact, safe, and reliable alternative to traditional substations. Its versatility, efficiency, and adherence to international standards make it an ideal choice for a wide range of applications.
