    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

    Q What is the working principle of an oil-immersed power transformer?
    An oil-immersed 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. The transformer oil surrounding the core and windings serves as both an electrical insulator and a cooling medium to dissipate heat generated during operation.
    Q What is the difference between a step-up and a step-down transformer?
    The difference lies in the turns ratio between the primary and secondary windings. A step-up transformer has more turns in the secondary winding than the primary, increasing the output voltage. A step-down transformer has fewer turns in the secondary winding, reducing the output voltage. Both types use the same electromagnetic induction principle.
    Q What international standards does this power transformer comply with?
    This power transformer is designed and tested in accordance with IEC 60076, the internationally recognized standard for power transformers. Compliance with this standard ensures operator safety, reliable performance, and seamless integration into existing power distribution systems worldwide.
    Q How does the fully sealed tank design benefit long-term performance?
    The fully sealed tank structure prevents moisture and air from entering the transformer, which protects the insulating oil from oxidation and contamination. This significantly extends the lifespan of the insulating oil, reduces the frequency of maintenance and oil replacement, and ensures stable electrical performance over the long term, even in humid or harsh outdoor environments.
    Q In which industries and applications can this power transformer be used?
    This power transformer is suitable for a wide range of applications, including power distribution utilities, industrial facilities (steel, cement, mining), renewable energy projects (solar farms, wind power plants), commercial and residential buildings, critical infrastructure (airports, railways, data centers), and the oil & gas sector. Its robust design makes it adaptable to both indoor and outdoor installations.
    Q What measures are taken to ensure low noise operation of the transformer?
    Low noise levels are achieved through precision core cutting and advanced assembly techniques that minimize magnetostriction — the slight physical deformation of the core material caused by the alternating magnetic field. By reducing this effect, the transformer produces significantly less operational noise, making it suitable for deployment in residential areas, hospitals, and other noise-sensitive environments.
