Magnetic Core Transformer Supplier

Transformer is a static electromagnetic device that converts electrical energy to magnetic energy and then back to electrical energy which is transferred between two or more circuits. According to their core structure, single-phase transformers with small and medium power can be divided into toroidal type (O type), EI type, R type, CD type, double column dry type, etc. Yet, the toroidal transformer is the most widely used because of its plentiful advantages. Toroidal core is closed and tightly winded with silicon steels. It is formed after vacuum pressure impregnation treatment. Even at middle and high magnetic frequency, it will not cause noise due to magnetic expansion, which is what the EI, dry-type, and other lamination cores cannot achieve. Toroidal core has good electromagnetic performance of high saturation magnetic flux density, high primary inductance, and large unit magnetizing power capacity. It helps improve the utilization rate and the winding window area, reduce the number of turns and the direct current resistance, and also greatly improve the overload capacity and load efficiency of the toroidal transformer. Under the condition of constant power and magnetic field density, the no-load loss and exciting current of toroidal transformer are only 50%~70% of other transformers. The toroidal core helps reduce the standby loss and improve the equipment operation reliability.
