Product Description

Distinguished Product Characteristics:
1. Crafted from premium-quality cold-rolled grain-oriented silicon steel sheets, the core features an innovative 45° three-stage fully oblique seam design. This meticulous craftsmanship ensures no punching for enhanced durability. The core column is expertly brushed with polyurethane varnish, providing superior curing and protection.

2. Engineered with precision, the coil utilizes oxygen-free copper conductors in a thoughtfully structured design. This strategic construction significantly boosts the coil's resilience against sudden short-circuits, ensuring reliability and stability.

3. By enhancing the effective support of the winding's end face, the short-circuit resistance of the winding is dramatically improved, setting a new standard for performance and reliability.

4. Revolutionizing traditional designs, the oil storage cabinet is eliminated, replaced by corrugated oil tank wave fins as efficient cooling elements. These wave fins dynamically expand and contract with the transformer's oil volume, isolating the oil from the atmosphere to prevent deterioration and dampness, thereby enhancing operational reliability. Maintenance-free for normal operations, this design ensures longevity and performance.
