Our Client List: 2009 Shanghai Expo 2008 Olympic Games Stadium Shanghai Pudong Airport Three Gorges Project Vietnam Song Power Station Korea Pusan the Second Steel Plant Iran Teheran Cement Plant ran Teheran the Third Chemical Plant Burundi Hydroelectric Station Malaysia Cement Plant Hydroelectric Station 10kv S13/S11 type low loss triangle roll core no-excitation and voltage regulating oil-immersed distribution transformer which inherited roll all the advantages of roll core transformer Core is rolled by machine totally Can eliminate inner stress after annealing treatment, no high magnetic resistance, so no-load loss and exciter current can drastically reduced, proved by test that no-load loss is only 50 to 60% of traditional transformer No-load current drop more than 90% Noise can reduce 10 to 15dB to mute Compare to traditional interpolation chip power transformer triangle stereo roll core power transformer has the following advantages: Prominent no-load loss reduced energy: 40 to 50% decrease load loss, 7 to 10 Reduce no-load current line loss: reduce 90% Silent: noise reduces 10 to 15 decibels No interference: magnetic flux leakage decrease by more than 50% Saving material: copper iron cost decreased 20 to 30% Economic benefit is remarkable: in ten years, working cost is 17.2% lower than S9, 12.5% lower than amorphous transformer
