Using high quality CRGO steels with low iron-loss and high permeability in thickness of 0.23mm, 0.27mm and 0.3mm.
Wound by a continouse silicon steel strips, cross-section is rectangular and also the window, flux path is absolutely closed, no magnetic leakage, so its magnetic performance is best of all.
The rectangular cores are suitable for manufacturing current transformers and potential transformers ranging from 0.38kV to 330kV in electrical industry.
The cores with high permeability and linear fully meet the requirement of measuring current transformers with accuracy class 0.1, 0.2, 0.5, 1.3 and 5.
The cores can also meet requirements of protection current transformer with accuracy of 5P and 10P as well as that of transient current tranformers.
