China Suppliers Factory Indoor Epoxy Resin Dry-Type Transformer SCB10 10kV Class 1 Energy Efficiency Low Noise
⚡ 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, and high-rise buildings, 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 makes the SCB10-10KV epoxy resin cast dry-type transformer suitable for indoor installation?
The transformer uses epoxy resin that 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 safe for indoor installation without the need for a dedicated transformer room.
Q
What is the partial discharge level of this dry-type transformer?
The windings are vacuum-impregnated with imported unfilled epoxy resin, forming a solid, bubble-free structure after curing. This process ensures an extremely low partial discharge level of ≤5 pC, which significantly enhances insulation reliability and service life.
Q
Can this transformer operate reliably in harsh environments such as high humidity or dusty conditions?
Yes. The moisture-resistant insulation system and specially treated core and clamps allow the transformer to operate reliably under harsh conditions including 100% humidity, high temperatures, and dusty environments — even after periods of intermittent use without prior drying procedures.
Q
What cooling methods are available for the SCB10-10KV transformer?
The transformer supports natural air cooling (AN) as the standard method. An optional forced air cooling (AF) system is also available, which can increase cooling efficiency by over 30%, making it suitable for applications with higher thermal demands or limited ventilation space.
Q
How does this transformer compare to traditional oil-immersed transformers in terms of size and weight?
Compared to traditional oil-immersed transformers, the SCB10-10KV dry-type transformer reduces overall volume by over 40% and weight by over 30%. This compact design allows for flexible installation in confined spaces and significantly reduces foundation and civil engineering requirements.
Q
What is the available rated capacity range for the SCB10-10KV transformer series?
The SCB10-10KV series covers a wide range of rated capacities from 30 KVA up to 2500 KVA, with a fixed short-circuit impedance of 6.5% across all models. This broad range makes it adaptable to diverse power distribution needs across industrial, commercial, and municipal applications.
