Main Characteristics:
1. Meticulously crafted with our patented technology and revolutionary software, this transformer guarantees exceptional performance and unmatched reliability.
2. The core, ingeniously constructed from top-tier cold-rolled, grain-oriented silicon steel sheets, employs advanced step-lap technology for peak efficiency and superior performance.
3. The windings employ high-tensile enameled wire, paper-insulated wire, or copper belt, ensuring consistent ampere-turn distribution, a robust insulation framework, and remarkable short-circuit resilience.
4. The corrugated oil tank exhibits outstanding corrosion resistance. Utilizing globally renowned brands for surface treatments and coatings, the tank undergoes comprehensive degreasing, pickling, phosphorating, electrophoresis, followed by a precise powder spray coating and heat-solidification process.
5. The active components benefit from a core-free hanging structure, equipped with gaskets crafted from premium-grade acrylate rubber, significantly reducing ageing under sun and heat exposure.

Advantages:
1. Experience extraordinary operational efficiency with minimal loss, reduced noise, low partial discharge, and exceptional reliability.
2. Unrivaled safety paired with a sleek and sophisticated design.
3. The corrugated oil tank delivers superior cooling performance and the flexibility to adapt to thermal-induced shape changes seamlessly.
4. Benefit from straightforward installation and maintenance, ensuring long-lasting usability.
5. Boasting a compact design, this transformer saves space with its minimalistic footprint.
Engineered for high efficiency, minimal energy loss, reduced noise, formidable load endurance, and an extended lifespan.


Applications
