Low loss: the dry type transformer with solid core coils is characterized by small seamless reluctance, magnetic circuit at the corner in the same direction as the magnetic conductivity of silicon steel sheet, high winding compactness and filling coefficient, and light weight of core. Compared with the traditional stacked core dry 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 solid coil core dry type transformer is 6-10 db lower than that of laminated core dry type transformer.
Low local discharge: the insulation of the wire turns of the product is made of NOMEX paper, which is non-toxic and flame retardant. NOMEX paper is a C grade insulation material that can withstand the temperature of 220c for a long time. The coils are vacuum-coated and the interturn layers are completely soaked without bubbles. Partial discharge of the product is controlled below 5PC.
High mechanical strength: the solid core is round section, the ability of short circuit resistance is better than the long section. The coil strength is high after the vacuum dip paint, adopt the special fastening way, the product can withstand the sudden short circuit electric power without damage.
