Performance Features

Low Losses: The product features more than a 20% reduction in no-load losses compared to SCB11 models, resulting in excellent energy savings, economic operation, and maintenance-free performance.

Low Noise: The product's noise level is 10-15 decibels lower than the current standard JB/T10088-2004’6-220 kV transformers sound level’.

Low Partial Discharge (Low PD):The resin mixture uses advanced foreign stirring methods and vacuum film degassing technologies to ensure uniform mixing and completely eliminate air bubbles. The product exhibits extremely low levels of partial discharge. Both high and low-voltage coils are cast under vacuum and pressure, providing resin insulation that features both full encapsulation and effective layer-to-layer impregnation. The cast body has a dense solidified structure that is flame-retardant, explosion-proof, and environmentally friendly.

The glass fiber and other insulating materials used in the winding coils have self-extinguishing properties, preventing arcing in the event of a short circuit, and the resin does not emit toxic or harmful gases even under high temperatures.

High Mechanical Strength: The resin with fillers reduces the coefficient of expansion differences within the cast body, resulting in low curing shrinkage and internal stress. The cured material has high hardness. Prefabricated reinforcing materials are placed within the epoxy resin encapsulation layer on both the inner and outer surfaces of the high and low-voltage coils, creating a dense structure similar to reinforced concrete. Consequently, the mechanical strength exceeds that of pure epoxy resin, allowing it to withstand sudden short-circuit electrodynamic forces without damage.
