SGB13 dry-type power transformer product features Low loss: the no-load loss of the product is reduced by more than 20% compared with the SCB11 product, with excellent energy-saving effect, economical operation, and maintenance-free. Low noise: The noise level of the product is more than 10-15 decibels lower than the current professional standard JB/T10088-1999 "6-220KV transformer sound level". Low partial discharge: The resin mixture adopts advanced mixing methods and vacuum film degassing technologies to make the mixture uniform and eliminate bubbles in the mixture. The product has only very low partial discharge, which can be controlled below 5PC.
Characteristics
High mechanical strength: The resin with filler makes the expansion coefficient difference in the casting body small, the curing shrinkage rate is small, the internal stress is small, and the hardness of the cured product is high. In the epoxy resin encapsulation layer of the inner and outer surfaces of the high and low voltage coils, there are The prefabricated reinforcing material has a dense structure like reinforced concrete, so the mechanical strength is greater than that of pure epoxy resin, and it can withstand the sudden short-circuit electromotive force without damage.
