Product Description

Distinctive Product Characteristics:
1. Crafted with precision, the core boasts superior quality cold rolled grain oriented silicon steel sheet, complemented by 45° three-stage fully oblique seams. This meticulous design ensures no punching, while the core column is expertly brushed with durable polyurethane varnish for exceptional curing.

2. Engineered with precision, the coil is constructed from oxygen-free copper conductor, featuring a thoughtfully crafted structure that greatly enhances its ability to withstand sudden short-circuits, ensuring robust performance.

3. The winding end face is effectively reinforced, significantly boosting the winding's short-circuit resistance, ensuring durability and reliability under demanding conditions.

4. By eliminating the oil storage cabinet, the innovative design introduces the wave fin corrugated oil tank, replacing traditional oil pipes as the primary cooling element. This allows the wave super to seamlessly expand and contract with the transformer's oil volume changes, effectively isolating the oil from the atmosphere. As a result, this ingenious approach prevents and reduces oil quality deterioration and insulation moisture, thereby enhancing operational reliability and ensuring maintenance-free normal operations.
