Power Transformers from China Factory - Reliable Suppliers for Efficient Energy Transmission and Distribution
Working Principle
This transformer operates on the fundamental principle of electromagnetic induction. It consists of primary and secondary windings wrapped around a laminated ferromagnetic core. When an alternating current (AC) flows through the primary winding, it generates a varying magnetic flux in the core. This magnetic field induces a voltage in the secondary winding, effectively transferring electrical energy from one circuit to another. The ratio of turns between the primary and secondary windings determines whether the voltage is increased (step-up) or decreased (step-down). The core and windings are submerged in high-dielectric insulating oil, which not only provides electrical insulation but also efficiently dissipates the heat generated during operation, ensuring long-term stability.
