Oil-Immersed Transformer Performance Features

a. The low-voltage winding of oil-immersed transformers typically uses a cylindrical structure wrapped with copper foil, except for small capacities which employ copper conductors. The high-voltage winding is structured in multi-layer cylindrical form to ensure balanced distribution of ampere-turns, minimal leakage flux, high mechanical strength, and strong short-circuit resistance.

b. Core and winding components are secured with locking nuts, and the tall body and low-voltage leads of the device feature self-locking anti-loosening screws. The design incorporates a non-swing core structure, capable of withstanding transportation vibrations.

c. Coils and cores are vacuum dried, and transformer oil is processed using vacuum filtration and filling techniques, which reduces moisture inside the transformer.

d. The fuel tank features corrugated sheets, which have a breathing function to compensate for the volume changes of oil due to temperature variations. Consequently, this product does not require an oil storage chamber, thereby significantly reducing the transformer's height.

e. By replacing the oil storage tank with corrugated plates, the transformer oil is effectively isolated from the outside environment, thereby preventing the entry of oxygen and moisture, which in turn helps maintain optimal insulation performance.

f. Based on the aforementioned five performance points, it ensures that the oil-immersed transformer does not require oil changes during normal operation, significantly reducing maintenance costs and extending the transformer's lifespan.
