The wide application of transformers and current transformers has promoted the upgrading and rapid development of the core industry, and the toroidal core is one of the high-quality cores. The O core independently developed by Nicore is a special type in the toroidal core.

In the raw material, like the toroidal core, the O core of Nicore adopts the high magnetic induction ultra-thin CRGO steel produced by Japan and South Korea, and can be made into different sizes according to the drawings while ensuring high-quality magnetic properties. In the production process, the CRGO steel is divided into curve strips by using automatic equipment, and then the loop winding machine is used for rapid winding forming, and the production efficiency is extremely high. After high vacuum annealing, the performance is stable and the size is accurate. Structural features, the O core is a circular or elliptical annular core wound by a curved CRGO steel. It is a paramagnetic ring structure, the magnetic circuit is completely closed, no magnetic leakage, and the magnetic properties are extremely Excellent; it can also be divided into an OA core with a circular cross section and an OB core with an elliptical cross section according to the cross-sectional shape.

The O core has the advantages of both the R core and the toroidal core, so the performance is excellent, and the price is cheaper than the R core, and has the advantage of customized specifications. The cost performance is extremely high, and can be used for HIFI sound, precision instruments, 400Hz transformers and electromagnetic components such as transformers and reactors.
