    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
    What is the basic working principle of a distribution transformer?
    A distribution transformer works on the principle of electromagnetic induction. Alternating current in the primary winding creates a varying magnetic field in the laminated silicon steel core, which then induces a corresponding voltage in the secondary winding. The ratio of input to output voltage is determined by the turns ratio of the two windings.
    What type of insulation oil is used in distribution transformers, and what is its purpose?
    Distribution transformers are typically filled with mineral insulating oil. This oil serves a dual purpose: it acts as a dielectric medium to provide electrical insulation between live components, and it functions as a coolant by carrying away heat generated by core and copper losses, maintaining safe operating temperatures.
    What international standards do your distribution transformers comply with?
    Our distribution transformers are designed, tested, and manufactured in full compliance with IEC 60076 and other relevant international standards. This ensures they meet the highest benchmarks for safety, interchangeability, and compatibility with utility grids worldwide.
    What installation options are available for distribution transformers?
    Distribution transformers are available in two primary installation configurations: pole-mounted (overhead installation on utility poles, suitable for rural and suburban areas) and pad-mounted (ground-level installation inside a sealed enclosure, ideal for urban environments, commercial buildings, and underground cable networks).
    Can distribution transformers be used with solar rooftop systems?
    Yes. Distribution transformers are well-suited for grid-tied solar rooftop installations. They provide essential voltage matching between the inverter output and the utility grid voltage level, as well as electrical isolation between the photovoltaic (PV) array and the grid, ensuring safe and efficient solar energy delivery.
    How does the hermetically sealed tank design benefit long-term performance?
    The hermetically sealed tank design prevents moisture ingress and oil contamination from the surrounding environment. This greatly reduces the risk of insulation degradation over time, leading to significantly lower maintenance requirements and ensuring decades of reliable, trouble-free operation even in harsh outdoor conditions.
