Product Description



Oil-immersed transformer:
1. Crafted with precision, the transformer core is composed of premium imported high-quality cold-rolled silicon steel sheets, significantly minimizing both no-load loss and no-load current, while effectively diminishing noise levels.
2. Ingeniously isolated from air exposure, the transformer design notably decelerates the aging process of both oil and insulation, enhancing longevity.
3. Equipped with a Dyn11 connection group, the transformer effectively mitigates harmonic interference, thus elevating the power grid's quality and stability.
4. With a fully sealed structure, this transformer boasts an extended service life, eliminating the need for core maintenance, ensuring reliability.
5. Impressively, the noise measurements fall below standard levels, assuring a quiet operational environment.
Excellent cooling performance:
Utilizing oil as a cooling medium, oil-immersed transformers excel at dissipating heat generated during operation, ensuring the system's enduring stability and safety.
Good insulation performance:
Possessing excellent insulation properties, transformer oil offers effective electrical isolation, guaranteeing the secure operation of equipment.
Strong overload capacity:
Engineered to endure substantial loads briefly, oil-immersed transformers exhibit remarkable overload resilience.
Long service life:
Thanks to meticulous design and superior material selection, oil-immersed transformers typically offer extended service life with minimal failure rates.
Large capacity adaptability:
These transformers can be tailored for large capacities, making them ideal for substantial power transmission and distribution needs.
Economical:
In expansive power facilities, oil-immersed transformers stand out for their relatively low investment and operating costs, delivering clear economic advantages.
