Product Description
Fully Sealed Oil-Immersed Distribution Transformer
This fully sealed oil-immersed distribution transformer is engineered for outdoor power distribution applications across a broad capacity range from 10 kVA to 2500 kVA. Featuring a hermetically sealed corrugated tank construction, the transformer completely isolates the internal insulating oil from atmospheric exposure, effectively preventing oil oxidation, moisture ingress, and contamination. The maintenance-free design eliminates the need for routine oil sampling, filtering, or refilling, significantly reducing lifecycle operational overhead. With advanced low-loss core materials, excellent heat dissipation through corrugated fins, and robust short-circuit withstand capability, this transformer delivers reliable, efficient, and long-term performance in diverse outdoor environments including urban distribution networks, industrial facilities, commercial buildings, and renewable energy installations
