R Series General Technical Specifications for Standard Products:

R-type Single-phase, Three-phase (SR) Transformer

LI020V11/2016

    1. Features:

R-type transformer is a rookie in dry-type transformer products. The iron core is made of high-quality oriented cold-rolled silicon steel strips of different widths and rolled into a round waist, and the cross-section is round, so it can be wound without cutting. Therefore, the transformer thus manufactured has no noise, small flux leakage, small no-load current, low iron loss, and high efficiency; and because the coil is cylindrical, the length of copper wire per turn is short, so the internal resistance is small and the copper loss is low. , low temperature rise, small overload fluctuation, and better explosive power than toroidal transformers; in addition, the primary and secondary coils are wound separately with skeletons made of flame-retardant PBT engineering plastics, so that they have high electrical strength and good flame retardancy.

R-type transformers are being favored by more and more electronic industries with their novel and unique structure and excellent electromagnetic properties. Especially suitable for medical equipment, display equipment, audio equipment, office equipment.
