HENTG 3150KVA 10/0.4KV Oil-Immersed Three-Phase Distribution Transformer
HENTG - Powering Your World with Reliability and Efficiency. Our premier outdoor distribution transformer is engineered for exceptional performance and durability in demanding environments. This 3150KVA, 10/0.4KV oil-immersed transformer is the ideal solution for commercial, industrial, and municipal power distribution networks.
Superior Performance with High-Efficiency Aluminum Windings
Features high-conductivity aluminum material for optimal performance and cost-efficiency. The design minimizes eddy current losses and ensures excellent heat dissipation, resulting in higher operational efficiency and lower energy costs.
Exceptional Durability for Harsh Outdoor Environments
Sealed, oil-immersed construction provides superior insulation and cooling, protecting against moisture, dust, and chemical contaminants. Corrosion-resistant exterior withstands extreme temperature fluctuations and heavy rain.
Enhanced Safety and Reliable Operation
Equipped with conservator tank to accommodate oil volume changes, preventing pressure build-up. Reliable insulating system reduces fire hazards while providing stable voltage step-down from 10KV to 0.4KV.
