Oil Immersed Transformer 13.8kV to 480V Yyn0 Connection ANSI UL Certified Distribution Transformer Manufacturer

Oil Immersed Transformer for Reliable Power Distribution

Our oil immersed transformer is engineered for high-efficiency power distribution and voltage transformation in industrial plants, commercial facilities, and utility substations. Designed as a three phase transformer, it delivers stable performance under heavy load conditions, making it an ideal solution for modern electrical systems.

Featuring advanced oil cooling technology (ONAN / ONAF / OFAF / OFWF), this oil filled transformer ensures excellent heat dissipation, reduced temperature rise, and extended service life. The sealed tank design effectively prevents oil leakage and enhances operational safety, even in harsh outdoor environments.

High Conductivity Copper Winding & Low Loss Design

Built with high-purity oxygen-free copper windings, this distribution transformer offers superior electrical conductivity and significantly reduced energy losses. Combined with high-grade silicon steel core, it achieves low no-load loss, low noise, and high energy efficiency, helping reduce operating costs.

The double winding transformer structure allows flexible voltage transformation, supporting a wide range of step down transformer applications such as 10kV to 400V, 13.8kV to 480V, and other customized voltage ratios

Flexible Configuration & Global Standards Compliance

This oil immersed distribution transformer supports multiple connection groups including Dyn11, Yyn0, Yd11, ensuring compatibility with various grid systems worldwide. It is fully compliant with IEC 60076, ANSI C57, UL, and CE standards, making it suitable for global export markets.

With customizable options for capacity (50kVA–2500kVA), voltage rating (up to 33kV), tap changer, and enclosure design, we provide tailored solutions to meet different project requirements.

Durable Structure & Long Service Life

The transformer features a corrosion-resistant galvanized steel tank, designed for pad-mounted outdoor installation. It is equipped with essential protection devices such as pressure relief valve, oil level indicator, and temperature monitoring system, ensuring safe and reliable operation.

With a service life of over 30 years, this power transformer delivers long-term performance with minimal maintenance requirements.
