Power Transformer 230-242kV on-load-tap-changing power transformer is made of high-quality silicon-steel sheets, and laminated by steps. It is advantageous in low loss, low noise, low voltage partial discharge and high anti short-circuit capacity. The dynamical and thermal stability of this transformer, of which the coils are winded by high-quality oxygen-free copper wire as well as used pre-compressing brackets processes and interior and exterior structure. The transformer tank used wave form shell, has very nice appearance, the core is with D shape yoke and 45 angle seaming. The core and oil box are well fixed and well protected on moving.
Three-phase dual winding oil immersed power transformer with OLTC

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;
Low noise level: <60dB, about 20dB lower than that required in the national standard.
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;
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).
Beautiful appearance: oil tank bending corrugated structure, shot blasting de-dusting, powder EFI paint, wide fin radiator, never fade in color;
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.
