Frequently Asked Questions
What is a 3-phase oil immersed distribution transformer used for?
It is used to step down medium-voltage electricity to low-voltage power for distribution in utility, industrial, and commercial systems.
What capacities are available?
Standard capacities range from 30kVA to 2500kVA, with customized models available up to 5000kVA or above.
What vector groups are commonly used?
The most common vector groups are Dyn11 and Yyn0, with optional Yzn11 and Dyn5.
Can the transformer be customized for our market?
Yes. Voltage, capacity, tank design, tap settings, winding material, and branding can all be customized.
Which standards can be supported?
We support IEC 60076, ANSI, IEEE, and customized regional standards.
