Power & Distribution Transformers
Elsan Transformer is a specialist manufacturer of high-efficiency power and distribution transformers — engineered for tropical grid conditions and supplied to utilities, DISCOs, and industrial projects across Nigeria and West Africa. Manufactured in Turkey to IEC 60076 and ISO 9001:2015 standards since 2018.
25kVA – 50MVA
Elsan Transformer is a Turkish-manufactured product line offering one of the broadest transformer ranges available in the Nigerian and West African market — from compact 25 kVA distribution units to heavy-duty 50 MVA power transformers. Engineered for 11kV and 33kV networks, the two most common voltage classes used by DISCOs and industrial operators across the region.
ISO Certified
Every Elsan transformer is manufactured under a rigorous quality management system certified to ISO 9001, ISO 14001, and ISO 45001 standards. From raw material selection to final assembly, each unit undergoes comprehensive routine testing before dispatch — so you receive equipment you can depend on from day one
IEC 60076
All Elsan power and distribution transformers are designed and tested in full compliance with IEC 60076 — the internationally recognised standard for power transformers. This guarantees consistent electrical performance, dielectric integrity, and long-term reliability across all operating conditions and grid environments in Nigeria and beyond
High Efficiency &
High Performance —
Built Into Every
Transformer
Elsan Transformer is a Turkish manufacturer of high-efficiency power and distribution transformers, bringing internationally certified engineering excellence to utilities, electrical distribution companies, industrial plants, and infrastructure developers across Nigeria and the wider West African region. Founded in 2018 and manufactured in Turkey to IEC 60076 and ISO 9001 standards, Elsan transformers are precision-engineered to perform reliably under tropical grid conditions — high ambient temperatures, humidity, voltage fluctuation, and the demanding load profiles common across West African power networks.
In a relatively short time, we have built a strong reputation for delivering high-quality, reliable, and efficient transformer solutions that meet the power needs of some of Nigeria's most demanding grid and industrial environments. Our manufacturing range covers distribution transformers from 25 kVA to 2,500 kVA and power transformers from 3.15 MVA to 50 MVA — one of the broadest product ranges available from a single manufacturer serving the West African market.
We understand the unique challenges of power infrastructure in Nigeria and across West Africa — from high ambient temperatures and harsh environmental conditions to the growing demand for reliable grid supply in both urban centres and rural communities. Every Elsan transformer is engineered specifically to perform reliably under these conditions, maximising energy efficiency, minimising losses, and delivering consistent output across varying load profiles.
At Elsan Transformer, quality is not an afterthought — it is built into every stage of our process, from design and material selection through to winding, assembly, and final testing. We adhere to IEC 60076 and ISO manufacturing standards to ensure that every transformer leaving our facility meets the requirements of Nigerian grid codes and international best practice.
We work closely with Electricity Distribution Companies (DISCOs), generation companies, industrial operators, and engineering contractors across Nigeria, Ghana, Cameroon, Benin Republic, Niger, and the broader West African region — providing tailored transformer solutions, expert technical support, and responsive after-sales service.
Whether your project requires a standard distribution unit for a local feeder network or a fully custom-engineered power transformer for a major substation, our team is ready to help. Contact Elsan Transformer today and let us engineer the right solution for your power needs.
