Basic Info.

At TAILI, we manufacture single phase pole mounted transformers engineered for overhead power distribution systems. Our Oil Immersed Transformers are designed to deliver reliable voltage step-down performance for residential, rural, commercial, and light industrial applications where stable and efficient power supply is required.


Depending on your project needs, our transformers can be supplied with different kVA ranges, primary and secondary voltage configurations, insulation systems, and protection arrangements. We can also support specifications aligned with common utility expectations such as ANSI, NEMA, DOE, IEEE, and RUS-related requirements when required by the project.


Single Phase Pole Mounted Transformers are available in a wide range of power ratings to meet different distribution requirements, from compact low-capacity units for residential use to higher-capacity models for utility and commercial networks. Common capacity options include 5 kVA, 10 kVA, 15 kVA, 25 kVA, 50 kVA, 100 kVA, 167 kVA, 250 kVA, and 315 kVA, with custom ratings available upon request.
