Engineering Overview & Scope
Positive Power Cast Resin Dry-Type Transformers eliminate flammable oil entirely, utilizing pure epoxy resin vacuum casting with quartz flour filling. This delivers outstanding dielectric insulation, self-extinguishing flame resistance, and moisture impermeability.
Classified under Environmental Class E2, Climatic Class C2, and Fire Behavior Class F1 per IEC 60076-11, it is safe for installation inside densely occupied spaces without requiring fire suppression blast walls or oil containment pits.
Key Engineering Advantages
- Complete fire resistance with self-extinguishing epoxy resin casting
- Zero oil leak hazard and zero toxic gas emission
- Class F (155°C) or Class H (180°C) high-temperature insulation
- Equipped with cross-flow forced cooling fans for +40% emergency overload capacity
- Digital PT100 temperature monitoring controller
Primary Industrial Applications
- ▪ Commercial High-Rise Buildings & Shopping Malls
- ▪ Underground Metro Rail Substations & Airports
- ▪ Data Centers & Telecom Central Switching Offices
- ▪ Cleanrooms & Pharmaceutical Packaging Facilities
