Our 10kV Dry-Type Power Transformers represent the safest and most reliable solution for modern indoor power distribution. Available in capacities from 400kVA to 2500kVA, these transformers utilize Epoxy Cast Resin technology, making them virtually maintenance-free and environmentally friendly.

The SCB10, SCB11, and SCB13 series are engineered for high-density environments where fire safety is paramount. Unlike oil-immersed units, these dry-type transformers are non-flammable and self-extinguishing. With superior resistance to short circuits and moisture, they are the primary choice for "zero-leakage" applications in commercial hubs, residential complexes, and critical infrastructure.

• Advanced Cast Resin Insulation: The high-voltage windings are vacuum-cast in high-grade epoxy resin, preventing moisture absorption and ensuring a high dielectric strength even in humid or polluted environments.

• Fire-Safe & Self-Extinguishing: Classified as F-Class (155°C) insulation, these units are non-explosive and produce no toxic gases, allowing them to be installed directly inside buildings without expensive fire-walls.

• Low-Loss Efficiency (SCB13): Our SCB13 models utilize high-permeability silicon steel cores to reduce no-load losses by up to 25-30% compared to standard SCB10 models, significantly lowering operational costs.

• High Overload Capacity: Equipped with axial cooling fans and a smart temperature control system, our transformers can handle a 40-50% short-term overload when forced-air cooling (AF) is activated.

• Low Partial Discharge: Vacuum casting technology ensures the partial discharge is kept below 10pC, which dramatically extends the service life and operational reliability of the windings.

1. High-Rise Commercial Buildings: Safe indoor installation in basements or rooftop substations for office towers and malls.

2. Data Centers: High-reliability power conversion for sensitive server infrastructure requiring clean, stable power.

3. Hospitals & Airports: Critical power distribution where fire safety and low noise levels are strictly regulated.

4. Subways & Tunnels: Durable, vibration-resistant transformers for metropolitan transit systems and underground infrastructure.

• Maintenance-Free Design: No oil level monitoring, no gaskets to replace, and no leakage risks. Periodic cleaning of the coils is the only required maintenance.

• Intelligent Temperature Control: Includes a three-phase PT100 thermal sensor system that provides real-time monitoring, alarm triggers, and automatic fan control.

• Robust Mechanical Strength: The fiberglass-reinforced resin casting provides exceptional resistance to mechanical stress and the electromagnetic forces generated during short circuits.

• Environmentally Sustainable: At the end of its service life, the resin and copper/aluminum components can be easily separated and recycled.

Q: Can this transformer be installed outdoors?

A: Dry-type transformers are primarily for indoor use. If outdoor installation is required, they must be housed in a specialized IP23 or IP33 protective enclosure to shield the coils from direct rain and debris.

Q: What is the difference between SCB10 and SCB13?

A: The main difference is the energy efficiency. The SCB13 is the high-efficiency model with a refined core design that offers much lower no-load and load losses compared to the older SCB10 standard.

Q: Do you offer copper or aluminum windings?

A: We offer both. While copper is the standard for high-conductivity and compact size, our high-quality aluminum winding models offer a more cost-effective solution with comparable thermal performance.

Dry type epoxy casting transtormer(SCB10, SCB11, SCB13-10KV)

• ◆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.

• ◆ Short circuit resistance,high lightning impact level,strong overload capacity.
