    Product Details

    Working Principle

    The New Energy Transformer operates on the fundamental principle of electromagnetic induction while incorporating design features tailored for renewable applications. It consists of primary and secondary windings around a laminated low-loss core. In solar applications, electricity generated by photovoltaic panels is converted to AC by inverters, and the transformer steps up this voltage (e.g., from 400 V to 11 kV or higher) for efficient long-distance transmission to the grid. For energy storage systems, the transformer enables bidirectional energy flow—stepping down grid voltage during battery charging and stepping up stored energy during discharge. The core and windings may be submerged in eco-friendly insulating fluids or encapsulated in cast resin, depending on the application requirements, providing both electrical insulation and efficient heat dissipation under variable loading conditions.
