Using high-quality CRGO steels with the characteristics of low iron-loss and high permeability in thickness of 0.23mm, 0.27mm, and 0.3mm.
It is wound by silicon steel strips and with a rectangular cross-section. The flux path is absolutely closed. No magnetic flux leakage. It has the best magnetic performance.
The rectangular cores are suitable for current transformers and potential transformers ranging from 0.38kV to 330kV.
The cores with high permeability and linearity fully meet the requirement of current transformers with accuracy of 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 transformers.
