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
Type LW24- /T outdoor H.V. A.C. dead tank SF6 gas circuit breaker is a new kind of circuit breaker with self-blast interrupter and spring operating mechanismon the basis of technology of product imported from Mitsubishi, Japan.The latest achieve—arc extinguishing principle of gas-blast pressure adapting with breaking-current is employed,by which most of energy required for breaking rated short-circuit current are acquired from arc itself.Therefore, the demand for operating power is reduced significantly. The three pole interrupters are placed inside three metal enclosures respectively. The circuit breaker can be mechanically three-phase gang-operated. Both remote electrical control and local manual control can be realized. Type CT20-II spring operating mechanism, provided with the product, is a kind of mechanism with low operating power, minimum maintenance work needed and high reliability. The product reaches international advanced level in the respect of main technical performance.
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.
