R-Core Transformer

No noise, small magnetic leakage, small no-load current, low iron loss, high efficiency; and because the coil is cylindrical, the length of the copper wire in each coil is short, so the internal resistance is small and the copper loss is low, the temperature rise is low, the overload fluctuation is small, and the explosive force is better than that of the toroidal transformer; in addition, the primary and secondary coils are respectively wound with skeletons made of flame-retardant PBT engineering plastics, resulting in high electrical strength and good flame retardancy

R-type transformer is a kind of new dry-type transformer products. Its iron core is made of high-quality oriented cold-rolled silicon steel strips of different widths and made into a waist circle, and the cross-section is circular, which can be wound without cutting. Therefore, the transformer thus manufactured has no noise, small magnetic leakage, small no-load current, low iron loss, and high efficiency; and because the coil is cylindrical, the length of the copper wire in each coil is short, so the internal resistance is small and the copper loss is low. , the temperature rise is low, the overload fluctuation is small, and the explosive force is better than that of the toroidal transformer; in addition, the primary and secondary coils are respectively wound with bobbin made of flame-retardant PBT engineering plastics, resulting in high electrical strength and good flame retardancy

  • About transformer core

    Electrical steel, usually referring to cold rolled electrical steel, can be divided into two major categories including grain oriented electrical steel and non-oriented electrical steel. Grain oriented electrical steel, with its easy magnetization direction parallel to the rolling direction, has excellent magnetic properties in this direction including low core loss, high permeability and low magnetostriction and is widely used in the transformer industry. Further it can obtain lower core loss by domain renement treatment. Meanwhile non-oriented electrical steel, featured by random distribution of grain orientation and magnetic isotropy, is widely applicable to the motor industry.
