5.11kv Three Dimensional Triangular Wound Core Transformer

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.

Product Details

Advantages

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.
