Our oil-immersed power transformers are rated up to 220kV and are type tested to IEC standards in KEMA (DNV) and ASTA. In the interest of keeping fossil fuels in the ground, we can offer non-mineral oils like ester oil.

Brunstock transformers include various types, such as hermetically-sealed, dry-type, amorphous alloy, pad-mounted, and other special transformers used in electrical furnaces, rectifiers, mines, lightning protection, arcs, as well as for current and voltage transducers. Brunstock can supply a wide range of series, types and specified transformers, with a manufacturing partner that has ample annual production capacity.

These transformer models have undergone theoretical analysis and simulation experiments in main insulation, longitudinal insulation, and the characteristics of winding impulse withstand voltage.

First-class power transformers

Quality control and management

Our manufacturing partners use advanced equipment for production, processing and testing to achieve high-quality power transformers that perform as expected. They have certificates for ISO 9001, ISO 14001, ISO 50001 and ISO 45001 for their company and European conformity (CE) certificates for their products. These quality control and management systems ensure the reliability and performance of Brunstock products.

Our transformers are available in:

• 220kV
• 110kV
