Current transformer
Currently, the company mainly produces three major categories of soft magnetic products:
1. High and low voltage current transformers for large transformers, GIS, and switchgear;
2. Soft magnetic toroidal cores and TPY cores for transformers;
3. High permeability materials containing 80% nickel and 5% molybdenum permalloy punchings, various cores, magnetic shielding covers, etc., for sensors and clamp meters.
Details
The main features of the current transformers produced by our factory are high precision, low ratio, and small size. It is a good product for users to adjust load, save electricity and improve economic efficiency. It is mainly used for testing and measurement of 10kV, 35kV, and 110kV vacuum switches and sulfur hexafluoride switches. It is widely used in the measurement of 110kV-500kV transformers, greatly improving the measurement accuracy. This product was used in the 500kV common transformers of the Three Gorges Project in 1999 and has been well received by users.
