Product Description



Oil-immersed transformer:
1. The transformer core is crafted from imported top-tier cold-rolled silicon steel sheets, significantly minimizing no-load losses and currents while diminishing operational noise.
2. Designed to be air-tight, this transformer is shielded from atmospheric exposure, thereby slowing oil degradation and insulation aging.
3. Employing a Dyn11 connection group, it effectively mitigates harmonic interference, enhancing power supply quality.
4. Its fully sealed construction not only prolongs its lifespan but also eliminates the need for core maintenance.
5. The noise level recorded is impressively below industry standards.
Excellent cooling performance:
Utilizing oil as a cooling agent, these transformers efficiently dissipate operational heat, ensuring equipment stability and safety.
Good insulation performance:
With exceptional insulating properties, transformer oil offers effective electrical isolation, guaranteeing safe equipment operation.
Strong overload capacity:
Capable of enduring high loads for brief durations, these transformers boast remarkable overload capacity.
Long service life:
Thanks to meticulous design and superior materials, these oil-immersed transformers promise longevity and minimal failure rates.
Large capacity adaptability:
Engineered for large capacities, they are ideal for high-power transmission and distribution scenarios.
Economical:
In expansive power setups, their investment and operational costs are notably low, yielding substantial economic returns.
