Low loss: due to the three dimensional coil core oil-immersed transformer has no joints of small magnetic resistance, corner magnetic circuit and the same magnetic direction of silicon steel sheet, winding compact packing coefficient high, core weight and other characteristics. Compared with the traditional iron-core oil-immersed transformer, the no-load loss Po can be reduced by 18%-28%. No - load current Io decreased by 50%-60%. Energy saving effect is remarkable, run economy.
Low noise: the noise level of the three dimensional coil core oil-immersed transformer is 5-10 db lower than that of the laminated core oil-immersed transformer. It is a perfect silent product.
High mechanical strength: the solid core is round section, the ability of short circuit resistance is better than the long section. And pad high coverage, good fastening effect, greatly improve the product's ability to withstand short circuit.
