11kv 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.
No-load current drop more than 90%
Noise can reduce 10 to 15dB.
S11-M.RL-80-2500/10-20 new energy-saving three-dimensional triangular wound core transformer (GB standard)
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
