China SCB10 10kV Class 1 Indoor Epoxy Resin Dry-Type Transformer - Energy Efficient, Low Noise Suppliers & 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
QWhat is an epoxy resin cast dry-type transformer and where is it typically used?
An epoxy resin cast dry-type transformer uses vacuum-impregnated epoxy resin to encapsulate the windings, eliminating the need for insulating oil. It is widely used in industrial parks, commercial complexes, municipal infrastructure, high-rise buildings, and load centers where safety, environmental protection, and compact installation are critical requirements.
QWhat makes the winding design of the SCB10-10KV transformer unique?
The high-voltage winding uses high-conductivity enameled copper wire with a high-temperature-cured insulation layer for superior dielectric strength. The low-voltage winding is wound with high-purity copper foil to maximize current capacity and heat dissipation. Both windings are vacuum-impregnated with imported unfilled epoxy resin, resulting in a bubble-free, solid structure with extremely low partial discharge of ≤5 pC.
QIs this transformer safe for indoor installation without a dedicated transformer room?
Yes. The epoxy resin used complies with the flame-retardant requirements of GB/T 10217-2018. The transformer is non-flammable, produces no toxic gases, and contains no volatile pollutants. These properties make it safe for direct indoor installation without requiring a separate transformer room.
QCan this transformer operate reliably in harsh or humid environments?
Yes. The moisture-resistant insulation system and specially treated core and clamps allow the transformer to operate reliably under extreme conditions, including 100% relative humidity, high temperatures, and dusty environments. It can even resume normal operation after intermittent use without requiring a drying process.
QWhat cooling options are available, and what overload capacity does it support?
The transformer supports natural air cooling (AN) as the standard option. An optional forced air cooling (AF) system is available, which can increase cooling efficiency by over 30%. The unit also supports a 120% short-term overload capacity, providing operational flexibility during peak demand periods.
QHow does the SCB10-10KV compare to traditional oil-immersed transformers in terms of size and maintenance?
Compared to traditional oil-immersed transformers, the SCB10-10KV reduces overall volume by over 40% and weight by over 30%, enabling flexible installation in compact spaces with minimal civil foundation work. It is fully sealed and maintenance-free, completely eliminating the risk of oil leakage and the associated maintenance costs.
