for your
power
needs.
Experience the excellence in power transformation.
Our
products are designed for long-lasting performance and efficiency.

Our transformer is meticulously crafted, featuring a robust iron core made from high-grade silicon steel sheets and epoxy resin cast coils. An insulation tube strategically placed between the high and low voltage coils enhances electrical insulation. Additionally, the coils are securely supported and constrained by a precision-engineered pad. [6]
Intricate Structural Properties:
(1) Solid insulation-wrapped winding ensuring superior safety and reliability.
(2) No wrapping winding designed for optimal performance.
Winding: The transformer comprises two windings: the high voltage winding dealing with higher voltages and the low voltage winding handling lower voltages.
Based on the relative positioning of these windings, high voltage windings can be classified into concentric type and overlapping type.
The concentric winding is straightforward and easy to manufacture, making it the preferred choice for all our designs.
The overlapping type is primarily used for specialized transformers, catering to specific requirements.

 

Exquisite Product Characteristics

Our SC(B)10 series 20kV and 35kV non-excitation voltage regulation dry transformers epitomize low-loss functionality.
Compliant with national standards GB6450, GB/T10228, and IEC726, these transformers boast the following superior characteristics:
1. Exceptional performance and minimal loss, serving as an upgraded replacement for the type 9 series.
2. Crafted from premium silicon steel sheets, significantly reducing magnetic flux density and operational magnetostrictive weight, thereby minimizing noise effectively.
3. Optimized high-voltage coil structure improves interlayer voltage and capacitance distribution, significantly enhancing the product's resilience to atmospheric and operational overvoltage. This also refines the electric field distribution, ensuring further efficiency.
4. Equipped with an advanced temperature control system and air cooling device, the fan cooling mechanism automatically activates under heavy load, greatly increasing the equipment's overload capacity.
