Low loss: The no-load loss of the product is more than 30% lower than that of the SCB10 type product, and the load loss is more than 10% lower than that of the SCB11 type product. It has excellent energy saving effect, economic operation and maintenance-free.
Low noise: the noise level of the product is 10-15 dB lower than the current standard JB / T10088-2016 "Sound Level of 6-220KV Transformer"
Low local discharge: The resin mixture adopts two advanced foreign mixing methods and vacuum film degassing technology to make the mixture evenly stir and eliminate bubbles in the mixture. The product only has a low partial discharge, which 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 immersion. The casting body has a dense curing structure, flame retardant, explosion-proof, and does not pollute the environment. Insulating materials such as glass fiber wound coils have self-extinguishing characteristics, and no arc will be generated due to short circuit, and the resin will not produce toxic and harmful gases under high heat.
High mechanical strength: The resin with filler makes the expansion coefficient difference of the casting body small, the curing shrinkage rate small, the internal stress small, the hardness of the cured product is high, placed in the epoxy resin encapsulation layer on the inner and outer surfaces of the high and low voltage coils The prefabricated reinforced material has a dense structure like reinforced concrete. Therefore, the mechanical strength is still greater than that of pure epoxy resin, which can withstand the sudden short-circuit electrodynamic force without damage.
