What Is a 6000 kVA Transformer?

A 6000 kVA transformer is a three-phase power transformer capable of handling 6,000 kilovolt-amperes of electrical load. It can step up or step down voltage between high-voltage transmission lines and local distribution systems. Typically oil-immersed and cooled by ONAN (Oil Natural Air Natural) or ONAF (Oil Natural Air Forced) methods, it delivers efficient thermal performance and long service life under demanding load conditions.

This transformer size fills the gap between medium voltage distribution and sub-transmission level systems and is commonly customized based on voltage ratings, cooling systems, and environmental requirements.
