Product Parameters

Oil-filled transformers, using liquid cooling, excel in outdoor settings due to their superior efficiency, extended lifespan, and reliable overload capacities. Our transformers are meticulously sealed, isolating them from external air, thus significantly delaying oil deterioration and insulation aging, thereby boosting operational reliability.
 

Features:
-Our three-phase oil-immersed distribution transformers are designed for high efficiency and minimal loss, leading to significant savings in power consumption and operational expenses.

-Featuring an innovative insulation structure, our transformer bodies are engineered to enhance resistance against short-circuits.

-Constructed from premium cold-rolled silicon steel sheets, the transformer core boasts exceptional magnetic conductivity.

-Employing high-quality oxygen-free copper wire, the core's high/low-voltage windings are crafted into a multi-layer cylindrical design.

-All fasteners undergo a special anti-loosening treatment, ensuring long-term stability.

-The oil tank features a corrugated structure with a cover and edges that are either thoroughly welded or securely bolted, remarkably extending the service life of both transformer oil and insulating materials.
