According to the different uses of the iron core, our company can produce various types of iron cores such as laminated iron cores, three-phase three-dimensional wound iron cores, and amorphous alloy iron cores.
Transformers are manufactured based on the principle of electromagnetic induction,and the magnetic circuit is the medium for electrical energy conversion.
The iron core is the main magnetic circuit of the transformer, and its main function is to conduct magnetism. It converts the electrical energy of the primary circuit into magnetic energy, and then converts the magnetic energy into the electrical energy of the secondary circuit.
At the same time, the iron core is also the mechanical skeleton of the transformer. The clamping device of the iron core not only makes the magnetic conductor a complete mechanical structure, but also has insulated coils sleeved on it, supports the leads, and installs almost all the internal components of the transformer.
The iron core has the largest weight among all the components of the transformer. It accounts for about 60% of the total weight in dry-type transformers and about 40% in oil-immersed transformers.
