250KVA Dry Type Transformer

This striking front-view image showcases our flagship 250KVA Dry Type Transformer in all its professional glory. Photographed in a clean, well-lit environment, the transformer’s robust and modern design is immediately apparent.

The sleek, low-profile enclosure, typically finished in a standard RAL color, is not just for aesthetics; it provides crucial protection against dust, moisture, and mechanical intrusion, ensuring reliability in harsh industrial settings.

The absence of an oil tank eliminates the risk of fire, making this 250KVA transformer the ideal safe choice for indoor installations close to sensitive loads. Prominent terminals and clear labeling hint at the ease of connection and maintenance. This image is designed to instill confidence, communicating key messages of quality, safety, and advanced engineering inherent in our Dry Type Transformer product line.

Photos détaillées

This detailed cutaway or close-up image is an engineering deep dive into the heart of what makes our 250KVA Dry Type Transformer so exceptional. We focus on four critical components:

1. Epoxy Resin Insulation: The coil is meticulously cast in a vacuum environment with premium-grade epoxy resin. This process creates a solid, monolithic insulation system that is completely impervious to humidity, prevents partial discharges, and offers exceptional resistance to thermal cycling and short-circuit stresses.

2. New Silicon Steel Core: The core is constructed from high-grain-oriented, low-loss silicon steel. This material, combined with advanced step-lap design, significantly reduces no-load losses and exciting current, directly contributing to the high energy efficiency of the 250KVA transformer.

3. 100% Copper Windings: Unlike aluminum or copper-clad alternatives, we use 100% electrolytic copper for all windings. Copper provides higher conductivity, better mechanical strength, superior thermal performance, and ultimately, a longer operational lifespan under heavy loading conditions.

4. Solid Heel Block & Insulation: The solid heel blocks and robust insulation system secure the windings, preventing movement and damage from electromagnetic forces during short-circuit events. This attention to mechanical detail ensures the structural integrity and long-term reliability of the Dry Type Transformer.

250KVA Dry Type Transformer Parameters

This comprehensive and clearly formatted data table provides all the essential engineering specifications required to evaluate and select our 250KVA Dry Type Transformer. It serves as a critical technical reference for consultants, engineers, and procurement specialists. Key parameters detailed include:

• Rated Capacity: Confirmed at 250KVA, defining its standard output.

• Voltage Combinations: Lists various standard High Voltage (HV) and Low Voltage (LV) options (e.g., 11kV/0.415kV, 22kV/0.415kV), demonstrating its flexibility for different grid connections.

• Connection Group: Typically Dyn11, which is standard for distribution transformers, providing a neutral point for grounding and handling unbalanced loads.

• Losses: Clearly states the guaranteed No-Load Loss and Load Loss (at specific insulation classes like F or H), which are vital for calculating the transformer’s lifetime operating cost and efficiency.

• No-Load Current: A low percentage value indicating the high quality of the magnetic core and the resulting energy efficiency.
  This transparency in data allows for precise system modeling and confirms that this 250KVA Transformer meets the exact requirements of your project.
