Product Description
220KV Oil-immersed Power Transformer copper coil for transformer
Product description:
01) Iron core is made of cold-rolled silicon-steel sheet with high conduction of magnetism and adopts pulling-plank structure,
so that its magnetic route is short, losses and noise level is low;
02) Compress wire is adopted for winding so losses are low and have good ability withstand short-circuit;
03) Its active part adopts special pressing method which could ensure reliable axial pressure;
04) The oil tank is bell type with the structure of full folding plate type, having an excellent exterior and easy for maintenance;
05) Adopting capsule-type oil container, it can reduce oil aging to the lowest degree.
06) Amount of local discharged: The apparent discharge amount is less than 80pC under the 1.5 times of rated voltage;
07) Noise: Products of 63MVA and below is lower than 58dB(AN);
08) Power loss: no-load loss is 30% lower than that of IEC standard;
09) Reliability: All in-service product have no damages or oil leakage occurred;
10) Short circuit withstanding: Model SFZ11-50000/132 smoothly passed the short-circuit withstanding test of the national
transformer quality supervision and inspection center and also passed Holland "KEMA" quality Control system.

•Coil : The high-voltage(HV) coil adopts an interleaved-continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed. All stays and pads are chamfered to keep highly reliable insulation.
•Core
1) The core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet and the material is cut with
advanced Germany Geoge GmbH automatic shear line with the cut burrs controlled within 0.02mm.
2) The silicon sheet fabrication adopts "no-upper yoke-lapped' technology and all lapped joints of the silicon sheet are 45 full-
miters. this effectively improves no-load performance and reduces noises.
Oil tank and accessories
The tank wall adopts wide steel sheet, which will be folded into corrugated structure without splicing , in this way welds are
decreased and mechanical strength is enhanced ; meanwhile , the corrugated wall has diverging effect, and thus plays a
role in decrease of noise.
Ville Electric Company will keep up with the century, the epoch,
Sincerely look forward to your cooperation and win-wimn!
