10KV Vacuum Cast Resin Dry Type Transformer 200 Kva Electric Mv Hv Transformers
The 10kV Cast Resin Dry-Type Transformer (SCB series) is a high-reliability power solution engineered for environments where fire safety and environmental protection are non-negotiable. Unlike traditional oil-filled units, these transformers utilize high-grade epoxy resin to vacuum-cast the high-voltage windings, making them virtually maintenance-free and self-extinguishing.
Available in SCB10, SCB11, and SCB13 efficiency tiers, our transformers are designed to meet various global energy standards. Whether you are powering a high-rise commercial building, a sensitive data center, or an underground subway system, our dry-type transformers deliver stable performance with low noise and zero risk of oil leakage.
-
Vacuum Cast Resin Technology: High-voltage windings are encapsulated in epoxy resin under vacuum. This ensures a partial-discharge-free operation (<10pC) and protects the core from moisture, dust, and corrosive fumes.
-
Superior Fire Safety: The materials are flame-retardant and self-extinguishing. In the event of an external fire, the transformer will not explode or release toxic gases, making it ideal for indoor installations.
-
High Overload Capacity: Engineered with excellent thermal stability, these units can operate at 120% of rated load for extended periods when equipped with our automated forced-air cooling (AF) fans.
-
Low Losses & High Efficiency: The SCB13 series utilizes optimized core stacking technology to reduce no-load losses by up to 25% compared to older SCB10 models, significantly lowering long-term operational costs.
-
Low Noise Operation: Precision-engineered core clamping and specialized damping materials ensure that noise levels remain well below industrial standards, suitable for residential and office environments.

-
Commercial High-Rises: Safe power distribution for shopping malls, hotels, and office skyscrapers where oil-filled transformers are restricted.
-
Data Centers & Hospitals: Critical infrastructure requiring highly reliable, low-interference power with minimal maintenance requirements.
-
Urban Transit Systems: Powering subway stations, airports, and railway signaling systems where space is tight and safety is paramount.
-
Industrial Manufacturing: Providing localized step-down power for clean rooms, pharmaceutical plants, and food processing facilities.
-
Intelligent Temperature Control: Every unit is equipped with a PT100 temperature sensing system and a digital controller that automatically triggers cooling fans and alarm/trip signals.
-
Environmentally Friendly: No oil means no risk of soil or water contamination. At the end of its long service life, the resin and copper/aluminum components can be safely recycled.
-
Compact Footprint: The high power density of our cast resin design allows for a much smaller footprint than traditional units, saving expensive floor space in urban electrical rooms.
-
Seismic Resilience: The rigid cast-resin structure provides excellent mechanical strength, making the unit resistant to vibrations and seismic shocks.
Q: What is the difference between SCB10, SCB11, and SCB13?
A: These numbers refer to the energy efficiency tier. As the number increases (from 10 to 13), the no-load losses decrease. SCB13 is the most energy-efficient model, offering the fastest return on investment through electricity savings.
Q: Can this transformer be installed outdoors?
A: Standard dry-type transformers are designed for indoor use (IP00). However, we can provide specialized IP23 or IP44 outdoor stainless steel enclosures with rain hoods and anti-condensation heaters for outdoor applications.
Q: Is it possible to customize the voltage ratio?
A: Absolutely. We can manufacture transformers with custom primary voltages (e.g., 6.6kV, 11kV, 20kV) and secondary voltages to meet your specific regional grid requirements.

The high-voltage winding is made of enamelled copper wire, and the low-voltage winding is made of copper foil. The high voltage winding is filled with glass fiber felt and poured by imported epoxy resin without filler in vacuum state. After curing, it forms a solid whole with high mechanical strength, less partial discharge and high reliability.
-
Flame retardant, explosion-proof,non-polluting, environmental friendly, can be installed in the load center.
-
The coil does not absorb moisture,the iron core, the clamp after special processing can be in 100% relative humidity and other harsh environment operation.Discontinuous operation without tide treatment.
