Product description Scb14 dry-type transformer is a new upgrading generation product. Its no-load loss reduces by 5% compared with model scb12,and 20% lower than that of scb11,showing significant energy-saving effect. Meanwhile, it is safe, fire-retardant, pollution-free, maintenance free and easy installation. With good moisture-proof performance, it can restart without pre-drying after shutdown. This model shows low loss, low partial discharge and low noise. Under forced air cooling, it can operate at 120% of ratedoverload. Perfect temperature protection and control system provides reliable guarantee for the safe operation of the transformer.
Product Features 1.Low loss: The no-load loss of the product is20%+lower than that of scb11 product, with good energy-saving effect, economic operation andfree formaintenance.
2.Low noise: The noise of this product is 10-15 dB lower than the "6-220 kV transformer soundlevel" of the current professional standard JB / T 10088-1999.
3.Low partial discharge:Adopt advanced mixing and vacuum membrane degassing technology to evenly mix the resin and remove bubbles in the mixture.This kind of raw material has dense solidification structure and can resist natural gas, explosion and environmental pollution.All high and lowVoltagecoils are injected under vacuum pressure.The local discharge electrode of this product is low and can be controlled below 5pc.
4.Safety materials:Glass fiber and other insulating materials have automatic stop characteristics, and resin will not produce toxic and harmful gas at high temperature,and will not produce arc when in short circuite.
5. High mechanical strength: filling resin reduces the difference of injection expansion coefficient, small curing shrinkage, small internal stress and high hardness of solidified body. The epoxy resin coating on the inner and outer surfaces of high and low voltage coils has the same structure as steel reinforced concrete. Its mechanical strength is greater than that of pure epoxy resin, and it can withstand the action of sudden short-circuit electrodynamic force without damage.
