1. Low loss: No-load losses is about 40% lower than that required in current national standard GB6451-1999;

Load losses is about 15% lower than that required in current national standard GB6451-1999;
2. Low noise level: < 60dB, about 20dB lower than that required in the national standard.
3. Low partial discharge: The full range process of 220kV product is dust-free operation; Metal

parts and insulation parts inside the transformer are all rounded; The partial discharge is

controlled to be lower than 70pc;
4. High short-circuit capacity: The independently designed SFP10-200000/220 transformer of

the Company has passed the short-circuit test of the National Transformer Quality Test &

Inspection Center (CTQC) (CTQC).
5. Beautiful appearance: Oil tank bending corrugated structure, shot blasting de-dusting, powder

EFI paint, wide fin radiator, never fade in color;
6. No leakage: All seal with limit position and upper & lower tank edges are sealed along two channels;

Sealing gasket is imported. We solemnly commit no leakage of oil.
