    Product Details

    Working Principle

    The Distribution Transformer operates on the principle of electromagnetic induction. It consists of primary and secondary windings mounted on a laminated silicon steel core. When alternating current flows through the primary winding, it creates a varying magnetic field in the core, which induces a voltage in the secondary winding. The voltage transformation ratio is determined by the turns ratio between the primary and secondary windings. Typically installed on utility poles (pole-mounted) or at ground level (pad-mounted), these transformers are filled with insulating oil that serves both as a dielectric medium and as a coolant, dissipating heat generated by core and copper losses to maintain optimal operating temperatures.

    Frequently Asked Questions

    QWhat is the working principle of a distribution transformer?
    A distribution transformer works on the principle of electromagnetic induction. Alternating current in the primary winding generates a varying magnetic field in the laminated steel core, which induces a proportional voltage in the secondary winding. The output voltage is determined by the turns ratio between the two windings.
    QWhat is the role of insulating oil in a distribution transformer?
    Insulating oil serves a dual purpose: it acts as a dielectric medium to provide electrical insulation between internal components, and it functions as a coolant by dissipating heat generated from core and copper losses, helping to maintain safe and optimal operating temperatures.
    QWhat international standards do your distribution transformers comply with?
    Our distribution transformers are designed, tested, and manufactured in accordance with IEC 60076 and other relevant international standards, ensuring safety, interchangeability, and full compatibility with utility grid requirements worldwide.
    QWhat installation types are available for distribution transformers?
    Distribution transformers are available in two primary installation types: pole-mounted transformers, which are installed on utility poles for overhead line systems, and pad-mounted transformers, which are installed at ground level and commonly used for underground distribution networks in urban and commercial areas.
    QCan distribution transformers be used in solar rooftop systems?
    Yes. Distribution transformers are widely used in grid-tied solar rooftop installations. They provide voltage matching and electrical isolation between the photovoltaic (PV) arrays and the utility grid, ensuring safe and efficient integration of solar power into the existing power distribution network.
    QHow does the hermetically sealed tank improve transformer reliability?
    A hermetically sealed tank completely prevents the entry of moisture and external contaminants into the transformer oil and internal components. This design eliminates oil oxidation and insulation degradation, significantly extending the service life of the transformer while minimizing the need for routine maintenance over decades of operation.
