China Suppliers Epoxy Resin Dry-Type Transformer SCB10 10kV Class 1 Energy Efficiency Low Noise Factory
⚡ Product Features
🔌
This epoxy resin cast dry-type transformer integrates advanced technology and high-quality materials, delivering excellent electrical performance, mechanical stability, and environmental adaptability. It is widely suitable for industrial parks, commercial complexes, municipal infrastructure, high-rise buildings, and similar applications, particularly for installation in load centers with strict requirements for safety, environmental protection, and space utilization.
🔧
The product features a differentiated conductor design. The high-voltage winding uses high-conductivity enameled copper wire with a high-temperature-cured insulation layer, offering high dielectric strength and stability. The low-voltage winding is wound with high-purity copper foil, providing ample cross-section, enhanced current capacity, and optimized heat dissipation. The windings are vacuum-impregnated with imported unfilled epoxy resin, forming a solid, bubble-free structure after curing. This ensures high mechanical strength, resistance to short-circuit forces, and extremely low partial discharge (≤5 pC).
🔥
The epoxy resin meets the flame-retardant requirements of GB/T 10217-2018. It is non-flammable, emits no toxic gases, and contains no volatile pollutants, allowing for safe indoor installation without a separate transformer room. The moisture-resistant insulation and specially treated core and clamps enable reliable operation in harsh conditions (e.g., 100% humidity, high temperatures, dusty environments), even after intermittent use without drying.
⚡
The transformer exhibits strong short-circuit and lightning impulse withstand capability, along with a 120% short-term overload capacity. Its thin insulation layers and conductive materials promote efficient cooling via natural air (AN); an optional forced air (AF) system can increase cooling efficiency by over 30%. The core is made of low-loss silicon steel, reducing no-load and load losses significantly below national standards for enhanced energy savings.
✅
Fully sealed and maintenance-free, it eliminates oil leakage risks. Compared to traditional oil-immersed transformers, its volume and weight are reduced by over 40% and 30%, respectively, allowing flexible installation in compact spaces with minimal foundation work.

❓ Frequently Asked Questions
Q
What is an epoxy resin cast dry-type transformer and where is it typically used?
An epoxy resin cast dry-type transformer is a type of transformer in which the windings are encapsulated in solid epoxy resin rather than immersed in oil. It is typically used in industrial parks, commercial complexes, municipal infrastructure, high-rise buildings, and other applications where safety, environmental protection, and space efficiency are critical requirements.
Q
Why is the partial discharge level so important, and what value does this transformer achieve?
Partial discharge indicates the quality of insulation within a transformer. High partial discharge can degrade insulation over time and lead to failures. This transformer achieves an extremely low partial discharge of ≤5 pC, thanks to vacuum impregnation with imported unfilled epoxy resin that forms a solid, bubble-free insulation structure, ensuring long-term reliability and safety.
Q
Is this transformer safe for indoor installation without a dedicated transformer room?
Yes. The epoxy resin used meets the flame-retardant requirements of GB/T 10217-2018. It is non-flammable, emits no toxic gases, and contains no volatile pollutants. These properties make it fully safe for indoor installation without requiring a separate transformer room, significantly simplifying building design and reducing construction costs.
Q
What cooling methods are available, and how much can forced air cooling improve efficiency?
The transformer supports natural air cooling (AN) as the standard method, utilizing its thin insulation layers and conductive materials for efficient heat dissipation. An optional forced air cooling (AF) system is also available, which can increase overall cooling efficiency by more than 30%, making it suitable for higher load demands or environments with limited natural airflow.
Q
How does this dry-type transformer compare to traditional oil-immersed transformers in terms of size and maintenance?
Compared to traditional oil-immersed transformers, this dry-type transformer offers significant advantages: its volume is reduced by over 40% and its weight by over 30%, enabling flexible installation in compact spaces with minimal foundation requirements. It is also fully sealed and maintenance-free, eliminating the risks of oil leakage and the associated maintenance costs.
Q
Can this transformer operate reliably in harsh environmental conditions such as high humidity or dusty environments?
Yes. The transformer is designed with moisture-resistant insulation and specially treated core and clamps, enabling stable and reliable operation in harsh conditions including 100% relative humidity, high temperatures, and dusty environments. It can even resume normal operation after intermittent use without requiring a drying process, making it ideal for demanding industrial and outdoor-adjacent installations.
