Product Description



Introducing our groundbreaking High Voltage 50kVA Oil Immersed Power Distribution Transformer Yyn0 Dyn11, an epitome of forward-thinking engineering and sustainability in the energy sector. Meticulously designed, this transformer harnesses the power of oil to serve as both an insulating and cooling medium, delivering exceptional power conversion capabilities and outstanding heat dissipation. Ideal for robust power transmission and distribution networks, it is expertly crafted to dramatically cut down on energy usage, boost grid efficiency, and minimize its environmental footprint, setting a new standard in ecological conscientiousness.
Key Features
1. Energy Efficient: With its state-of-the-art architecture, our transformer significantly reduces core and coil losses, enhancing energy conversion efficiency while
notably lowering operational energy costs. This positions it as a vital element in cost-efficient power solutions.
2. Low Loss: Constructed from top-tier silicon steel sheets and employing the latest manufacturing innovations, it minimizes no-load and load
losses, leading to marked reductions in total operational expenses and ensuring unrivaled economic efficiency.
3. Excellent Heat Dissipation: By employing oil as a cooling agent, it optimally disperses heat through either natural convection or forced oil
circulation, ensuring stable, trustworthy performance even in high-demand situations, thus prolonging equipment life.
4. Environmentally Friendly Design: Fully aligned with worldwide energy-saving and environmental regulations,
it significantly curtails carbon emissions and environmental impact, making it the perfect selection for green initiatives and cutting-edge eco-friendly power
grids, fostering a sustainable and environmentally responsible future.
5. Safe and Reliable: Built with premium insulation materials and exceptional craftsmanship, the transformer guarantees secure and steady
operation in demanding grid conditions, delivering trustworthiness and peace of mind.
