China Suppliers Factory Indoor Epoxy Resin Dry-Type Transformer SCB10 10kV Low Noise Energy Efficiency
⚡ 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 — ensuring 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 the partial discharge level of this epoxy resin cast dry-type transformer?
The transformer achieves an extremely low partial discharge level of ≤5 pC. This is achieved through vacuum impregnation with imported unfilled epoxy resin, which forms a solid, bubble-free insulation structure after curing, ensuring long-term electrical reliability and safety.
Q
Can this transformer be installed indoors 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. This makes it safe for direct indoor installation without requiring a separate transformer room, saving space and reducing civil construction costs.
Q
What cooling methods are available for this transformer?
The standard configuration uses natural air cooling (AN), which is enabled by the thin insulation layers and conductive materials that promote efficient heat dissipation. An optional forced air cooling (AF) system is also available, which can increase the cooling efficiency by over 30%, making it suitable for higher-load applications.
Q
Is this transformer suitable for use in harsh environments such as high humidity or dusty conditions?
Absolutely. The moisture-resistant insulation system and specially treated core and clamps allow the transformer to operate reliably in demanding environments including 100% relative humidity, high temperatures, and dusty conditions. It can even resume normal operation after intermittent use without requiring a drying process.
Q
How does this dry-type transformer compare to traditional oil-immersed transformers in terms of size and weight?
Compared to traditional oil-immersed transformers, this dry-type transformer offers a significant size and weight advantage — its volume is reduced by over 40% and its weight by over 30%. This allows for flexible installation in compact spaces with minimal foundation requirements, making it ideal for urban buildings and space-constrained facilities.
Q
What is the available capacity range, and does the transformer support overload operation?
The transformer is available in a wide capacity range from 30 KVA to 2500 KVA, covering most industrial and commercial application needs. It supports a 120% short-term overload capacity, providing operational flexibility during peak demand periods without compromising safety or service life.
