The cores are wound from grain oriented silicon steel strip and are annealed in high vacuum furnace.

The cores are wound from grain oriented silicon steel strip and are annealed in high vacuum furnace under protection atmosphere. Special tools warrantee a smooth external quality and accurate window dimensions. Comparing to step R-cores, rectangular core is easy to assemble and it has the same characteristics of toroidal cores of making full use of grain orientation of silicon steels. Applications:Power distribution transformers, current transducers, instrument transformers, inductors, special transformers.
