Amount of local discharged:The apparent discharge amount is less than 80pC under the 1.5 times of rated voltage; Noise: Products of 63MVA and below is lower than 58dB(AN); Power loss: no-load loss is 30% lower than that of IEC standard; Reliability: All in-service product have no damages or oil leakage occurred; Short circuit withstanding: Model SFZ11-50000/132 smoothly passed the short-circuit withstanding test of the national transformers quality supervision and inspection center and also passed Holland “KEMA” quality Control system.
1 Our SC(B) series epoxy resin cast dry transformer is cast under vacuum with thin insulating bands automatically. 2 The core is made of high-permeable grain-orientated silicon sheet and cast with imported epoxy resin. 3 The coil is reinforced with glass fiber and cast under vacuum with filer epoxy resin. 4 The high- and low-voltage systems are cast under vacuum, thus the coil will not absorb moisture. 5 The clamps of core are subjected to corrosion-resistant treatment and it may run under high temperature or other serious environments. 6 Flame retardancy, explosion-proof and no environmental contamination. 7 Gas duct is embedded inside it to enhance the radiation power and over-load capacity. 8 Low loss and low noise. 9 It highly withstands short-circuit and lightning impact. 10 Small in volume, light in weight, safe in running and free of maintenace. 11 As per users' requirements the transformer may be provided with casing and blower fan
