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.

1. Commercial High-Rises: Safe power distribution for shopping malls, hotels, and office skyscrapers where oil-filled transformers are restricted.

2. Data Centers & Hospitals: Critical infrastructure requiring highly reliable, low-interference power with minimal maintenance requirements.

3. Urban Transit Systems: Powering subway stations, airports, and railway signaling systems where space is tight and safety is paramount.

4. 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.
