SCB11 2500kva Three Phase Power Distribution Transformer Dry Type​

Low Loss: The no-load loss of the product is reduced by more than 20% compared with the SCB10 model, and the load loss is reduced by over 30%. It features excellent energy-saving performance, economical operation, and requires no maintenance.

Low Noise: The noise level of the product is 10-15 decibels lower than the current industry standard specified in JB/T10088-2016 Sound Level of 6-220KV Transformers.

Low Partial Discharge: The resin mixture adopts two advanced foreign technologies: sophisticated stirring methods and vacuum thin-film degassing. These ensure the mixture is uniformly blended and free of bubbles, resulting in extremely low partial discharge—controlled below 5PC. Both high-voltage and low-voltage coils are cast under vacuum and pressure, making the resin insulation not only fully encapsulated but also capable of impregnating between layers and turns. The cast body forms a dense cured structure, offering flame retardancy, explosion resistance, and environmental friendliness. Insulating materials such as glass fibers used in coil winding are self-extinguishing, preventing arc generation due to short circuits; additionally, the resin does not release toxic or harmful gases under high heat.

High Mechanical Strength: The filled resin minimizes differences in thermal expansion coefficients within the cast body, reduces curing shrinkage, and lowers internal stress, resulting in high hardness of the cured product. Preformed reinforcing materials are embedded in the epoxy resin encapsulation layers on the inner and outer surfaces of both high-voltage and low-voltage coils, creating a dense structure similar to reinforced concrete. This structure provides higher mechanical strength than pure epoxy resin, enabling it to withstand the electrodynamic forces of sudden short circuits without damage.
