Scb13 dry type power transformer

   Features of scb13 dry type power transformer

Low loss: the no-load loss of the product is more than 20% lower than that of scb11 product, with excellent energy saving effect, economical operation and maintenance free.

Low noise: the product noise level is 10-15 dB lower than the current professional standard JB / t10088-1999 "6-220KV transformer sound level".

Low partial discharge: the advanced mixing method and vacuum film degassing technology are adopted for resin mixture to make the mixture evenly mixed and eliminate the bubbles in the mixture. The product only has very low partial discharge, which can be controlled below 5pc. Both high and low voltage coils are poured under vacuum and pressure, so that the resin insulation has both full encapsulation and inter turn dip clearing. The casting body has a dense solidified structure, which is flame-retardant, explosion-proof and does not pollute the environment.

The glass fiber and other insulating materials of winding coil have self extinguishing characteristics, which will not generate arc due to short circuit, and resin will not produce toxic and harmful gas under high heat.

High mechanical strength: the resin with filler makes the expansion coefficient difference in the pouring 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 envelope of the inner and outer surfaces of the high and low-voltage coils, prefabricated reinforcing materials are placed, which have the same dense structure as steel reinforced concrete, so the mechanical strength is greater than that of pure epoxy resin, and it can withstand sudden changes Short circuit electrodynamic action without damage.
