E-Core

The cores are wound from grain oriented silicon steel strip and are annealed in high vacuum furnace under protection atmosphere. The impregnation is done in vacuum impregnating equipment, and low-stress and high-viscosity resin are being used. Fine polishing process of cutting surface ensures very good performance of the cores with low core loss and high saturation. We can also produce 'non-standard' cores according to customers' specifications. Applications: Power transformers, current transducers, instrument transformers, inductors, chokes, ballasts, voltage stabilizers and regulators, welding transformers, special transformers
