This series of power transformer is a energy-saving product with high technology and performance, which reaches international advanced level of same type transformer. The transformer core adopting high permeability is wounded into enclosed type, and there will be no butt joint, annealing process of core can comb-out internal stress, and there is no high magnetic zone in magnetic circuit, thus sharp decreasing no-load loss and magnetic current. Comparing with S9 type power transformer, its capacity is down 30%, no-load current is down 70%, and the sound level is down 10dB. The transformer adopting full-sealing structure cancels conservator, thus isolating oil from external gas, in this case, the insulation is not easy to damp and the degree of aging is reduced, thus improving the reliability and operation life.
