Product Description: the performance index of dry-type transformer produced by our company conforms to various standards, which is proved to be reliable by users and reaches the advanced level in China. This series of products adopt foreign advanced manufacturing technology, the design drawings and technical documents are complete, correct and clear, the production equipment is advanced, the manufacturing process is stable, and the testing means are complete, which provides a solid guarantee for the production of excellent products.
Product features:
Low loss: the no-load loss of the product is more than 20% lower than that of the scb10 type product, and the load loss is more than 30% lower than that of the scb10 type 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 / t10088-2016 "6-220KV transformer sound level".
Low partial discharge: the resin mixture adopts advanced mixing method and vacuum film degassing technology to make the mixture evenly mixed and completely eliminate the bubbles in the mixture. The product 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 castable body has a dense solidified structure, flame retardant, explosion-proof, no pollution to 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 has little difference in expansion coefficient in the pouring body, small curing shrinkage rate, small internal stress, and high hardness of the cured product. In the epoxy resin envelope on 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, which can withstand the sudden changes Short circuit electrodynamic action without damage.
