Product overview

Low loss: The three-dimensional coiled core dry-type transformer has the characteristics of small seamless magnetoresistance, uniform magnetic conduction direction between corner magnetic circuit and silicon steel sheet, high coiling compact filling coefficient and light core weight. Compared with the traditional laminated core dry transformer, the no-load loss Po can reduce 18%-28%. No load current Io decreased by 50%-60%. The energy saving effect is remarkable and the economy is running.

Low noise: the noise level of the dry-type transformer with three dimensional wound core is 5-10 dB lower than that of the stacked core dry transformer.

Low partial discharge: Resin mixing material adopts the most advanced mixing method and vacuum film degassing technology, so that mixing material stirring evenly, completely eliminating the bubbles in the mixture, high and low pressure coils are poured under vacuum pressure, resin insulation has full encapsulation, and there is complete immersion between layers and turns. The partial discharge of products is controlled below 5PC. The pouring body has a compact curing structure, flame retardant, explosion-proof, and does not pollute the environment.

High mechanical strength: the three-dimensional coil iron core uses a regular circular section, the ability to resist short circuit is better than the long circular section. The resin with filler makes the expansion coefficient of the pouring body small difference, curing shrinkage rate small, internal stress small, hardness of the cured material high, in the inner and outer surface of the high and low pressure coil epoxy resin envelope inside the placement of prefabricated reinforced materials, with the same compact structure as reinforced concrete, so the mechanical strength is far greater than pure epoxy. Therefore, the product can withstand sudden short circuit electric power without damage.
