R-Core

The cores are wound from grain oriented silicon steel strip, which is silted into curve by computer control slitting machine. The external shape is rectangular and the cross-section is round. The cores are annealed in high vacuum furnace under protection atmosphere. The impregnation is done in vacuum impregnating equipment. The R-core transformers have advantages of compact dimension, high efficiency, low magnetic leakage, reliable safety and easy winding. Many transformer designers consider it as an ideal transformer structure. Applications: Power transformers, current transducers, instrument transformers, inductors, chokes, AF transformers, magnetic amplifiers, voltage stabilizers and regulators, special transformers
