Advantages of O Type Power Transformer
Generally, the sound of toroidal transformer is good, large dynamic, less magnetic leakage, more quiet, and low temperature. R type transformer’s voice is warm, low internal resistance, excellent high frequency extension and also the subtle state is very good.
Compared with toroidal transformer, O type transformer has the following advantages:
a. The average length of the coil is reduced by 11.4%-30%;
b. The coil has no folding angle, which makes the magnetic field distribution more uniform. For Structural features, the core has no fracture, the section is approximately circular and like as an oblate structure, also its height is short and diameter is larger with more uniform structure, so that its leakage magnetic is smaller.
Compared with the R-type transformer, its coil is not limited by the skeleton, and is tightly attached to the core, which is better coupled and more efficient. O-type transformer’s sound quality at sweet and warm aspect has a significant difference in actual comparison with the other transformers.
