SCB13 dry type power transformer product features. Low loss: the no-load loss of the product is 20% lower than that of the SCB11 product, and the energy saving effect is excellent, running economy and maintenance free. Low noise: product noise level is 10 to 15 decibels lower than the current professional standard JB/ t10088-1999 "6-220kv transformer sound level". Low set: resin mixed materials adopt the most advanced mixing method in foreign countries and vacuum film degassing technology, so that the mixture is evenly mixed and the bubbles in the mixture are excluded. The product only has extremely low local discharge, can be controlled under 5PC. The high and low pressure coils are poured under vacuum and pressure, so that the resin insulation can be both encapsulated and inter-turn. The casting body has a dense solidified structure, which is resistant, explosion-proof and pollution-free. The glass fiber and other insulating materials of winding coil have self-extinguishing characteristics, which will not cause the electric arc of short circuit, and the resin will not produce poisonous and harmful gas in high heat. High mechanical strength: packing resin to make casting body expansion coefficient difference is small, small curing shrinkage rate, small internal stress, curing of high hardness, the internal and external surfaces of the high and low voltage coil epoxy resin coating layer, placed with the strengthening of prefabricated molding material, especially as dense as the reinforced concrete structure, and mechanical strength is greater than the pure epoxy resin, can withstand the sudden and short-circuit force without damage.
