SCB13 series resin insulation dry-type transformers

Performance Characteristics

Low loss: 

The no-load loss of the product is more than 20% lower than that of the SCB11 product. It has excellent energy saving effect, economical operation and maintenance-free.Low noise: The product noise level is more than 10-15 decibels lower than the current professional standard JB/T10088-1999 "6-220KV Class Transformer Sound Level".

Low partial discharge: 

The resin mixed material adopts the most advanced foreign mixing method and vacuum film degassing technology to stir the mixture evenly and eliminate air bubbles in the mixture.The product has very low partial discharge and can be controlled below 5PC.The high and low voltage coils are cast under vacuum and pressure, so that the resin insulation has both full encapsulation and inter-turn leaching properties.The pouring body has a dense solidified structure, which is fire-resistant, explosion-proof and does not pollute the environment.Insulating materials such as fiberglass wound around the coil have self-extinguishing properties and will not generate arcs due to short circuits. The resin will not produce toxic and harmful gases under high heat.

High mechanical strength: 

The resin with fillers makes the difference in expansion coefficient of the casting body small, the curing shrinkage rate is small, the internal stress is small, and the hardness of the cured p

roduct is high. In the epoxy resin encapsulation layer of the inner and outer surfaces of the high and low voltage coils, there are placed The prefabricated reinforced material has a dense structure like reinforced concrete, so its mechanical strength is greater than that of pure epoxy resin, and it can withstand sudden short-circuit electric forces without damage.
