ENERGOIN’s oil-filled distribution transformers stand for high reliability, long service life, and precise manufacturing quality. They are designed for safe and efficient use in power distribution networks and cover power ranges from 100 to 5000 kVA at voltages up to 36 kV.
Through the use of modern production technologies, carefully selected components, and high-quality materials, our transformers meet the highest technical requirements. Each transformer is manufactured and tested according to stringent quality standards to ensure stable performance and maximum operational safety.
Thanks to their robust construction and optimized cooling, our oil-filled distribution transformers are particularly durable and require minimal maintenance. They are ideally suited for applications in industrial plants, power grids, infrastructure projects, and renewable energy facilities.
ENERGOIN’s oil-filled medium-power transformers are designed for demanding applications in power transmission and distribution. With power ranges from 5 to 10 MVA and voltages up to 36 kV, they offer a reliable and efficient solution for modern energy infrastructures.
We develop and supply customized transformers precisely tailored to your technical and operational requirements. Precise design, high-quality materials, and state-of-the-art manufacturing technologies ensure our products offer high operational reliability, stable performance, and a long service life.
Whether used in power plants, energy distribution networks, or industrial facilities, our transformers impress with their reliability, efficiency, and robustness in daily operation. Thanks to a wide range of design and equipment options, our solutions can be flexibly adapted to varying network conditions, environmental factors, and specific project requirements.
Power transformers are devices used in electricity transmission and distribution networks to compensate for the voltage difference between the primary (input) and secondary (output) sides.
These transformers are custom-built starting at 5000 kVA and 110 kV. Power transformers offer a wide range of technical characteristics, including power output, voltage, and voltage regulation.
Each transformer is individually designed to meet specific requirements and environmental conditions. Factors influencing the transformer’s efficiency and performance are carefully considered during the design phase. Our transformers comply with international standards EN 60076-1, BS 171, DIN, ANSI, ENEL CSA, and European Directive 548/2014 (Tier 1 & Tier 2).
ENERGOIN cast resin transformers offer a safe, reliable, and environmentally friendly solution for power distribution. With power ranges from 250 kVA to 20 MVA and voltages up to 36 kV, they are suitable for numerous applications in industry, infrastructure, and building technology.
Our transformers are manufactured according to the international quality and environmental standards ISO 9001 and ISO 14001. The vacuum cast resin coil technology ensures high resistance to moisture, dust, and contaminated environments, guaranteeing reliable operation even under demanding conditions.
Depending on requirements, we manufacture our transformers using either the VI (vacuum impregnation) or VPI (vacuum pressure impregnation) process. This achieves optimal penetration of the impregnating resin, further improving electrical insulation, mechanical strength, and service life.
ENERGOIN cast resin transformers comply with the EU Ecodesign Directive (EU 548/2014) and the standard IEC 60076-11:2018-10.
With production sites in Bosnia and Turkey, as well as an office in Germany, we have an international presence.
Our experienced specialists ensure precise manufacturing and the highest quality for every transformer.
All products are manufactured according to IEC 60076, EU Ecodesign 548/2014 and ISO certifications.
We produce up to 400 distribution transformers and 30 power transformers + 90 cast resin transformers per month.
