How Much Are Transformers?

The cost of transformers in Nigeria varies depending on factors such as capacity, voltage, and brand, with prices ranging from ₦8,294,000 for smaller units like the 100 KVA transformer to ₦75,358,000 for larger models. Understanding these costs is key to finding the best solution for your construction project’s power needs.

Transformers are essential for the transmission and distribution of electricity, as they step up or step down voltage to ensure a stable and reliable power supply. At OME, we recognize how vital consistent power is for any construction project, which is why we provide the right transformers to suit the specific needs of your industrial, commercial, or residential projects. Choosing the right transformer is crucial, and we’re here to guide you in making an informed decision.
