    Product Details

    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.

    Frequently Asked Questions

    What is the basic working principle of a power transformer?
    A power transformer works on the principle of electromagnetic induction. An alternating current in the primary winding creates a changing magnetic flux in the laminated core, which induces a corresponding voltage in the secondary winding, allowing electrical energy to be transferred between circuits at different voltage levels.
    What is the role of insulating oil in a power transformer?
    The insulating oil serves two critical functions: it provides high-dielectric electrical insulation between the windings and the tank, and it acts as a cooling medium to efficiently dissipate the heat generated during operation, ensuring long-term stability and performance.
    What international standards does this power transformer comply with?
    This power transformer is designed and tested in full accordance with IEC 60076, the internationally recognized standard for power transformers. This ensures operator safety, reliable performance, and seamless integration into existing power systems worldwide.
    Is this transformer suitable for outdoor installation in harsh environments?
    Yes. The transformer tank is treated with anti-corrosion paint and sealed with high-quality gaskets, making it fully capable of reliable performance in harsh outdoor environments with extreme temperatures or high humidity levels.
    Can this transformer be used in renewable energy projects such as solar or wind farms?
    Absolutely. This power transformer is well-suited for renewable energy integration applications. It can step up the voltage generated by solar panels or wind turbines to the required level for efficient transmission to the main power grid.
    How does the transformer achieve low noise during operation?
    Low noise is achieved through precision core cutting and advanced assembly techniques that minimize magnetostriction — the slight change in shape of the core material under a magnetic field. This makes the transformer ideal for use in residential areas or other noise-sensitive environments.
