MAXI – Indoor-Operated Substation
The adaptable substation
The MAXI series gives you room to secure stable power supply – today and in the future.
Our flexible MAXI series is developed for projects that demand high capacity, safety, and flexibility. The solution gives you room to handle both today’s needs and future changes in the installation.
MAXI gives you more capacity with options for larger transformers, different layouts, and customized switchgear setups. You get a solution that scales and evolves with your project requirements.
Wide Room To Maneuver
This series is our most versatile for indoor-operated substations, and we produce it in sizes from 2260 to 7235 mm. MAXI has room for one or more transformers in the same substation, with identical or different ratings.
From Standard to Special
MAXI covers everything from standard configurations to custom solutions with separate rooms, EKOM integration, and advanced high-voltage and low-voltage layouts. The substations can be built with ring foundations, oil collection, increased internal height, and in combination with other buildings and technical shelters.

Built to Last
Naturally Sustainable
The design uses Magnelis-treated steel and a solid, glass fiber–reinforced roof that delivers high corrosion resistance and long service life – even in harsh climates. The material choices ensure durable solutions that withstand both time and stress.
Natural ventilation, well-designed cable cutouts, and flexible foundation options ensure safe installation and stable operation. You get a solution that runs reliably for many years, with good conditions for easy installation and maintenance.
More of What Matters
If you design or order substations, MAXI gives you more of what matters: capacity that covers future needs, quality that lasts, and flexibility that lets us tailor the substation exactly to your project requirements, with no compromises.

Environment, Safety and Energy Efficiency
The future power grid demands responsible choices
Energy efficiency and sustainability are not add-ons
– they are basic requirements.
Our transformers comply with the EU’s ecodesign requirements and reduce energy losses throughout their entire lifetime. Over the full life cycle, high efficiency delivers significant energy savings.
Circular Economy in Practice
Up to 98% of the materials are recyclable. You can dismantle the components efficiently with low energy use.
Environmentally friendly and fire-safe solution
If needed, we deliver the transformers with natural ester oil (FR3) – with a very high flash point and high biological degradability.
Low noise level
The oil acts as a natural sound damper and reduces noise levels in densely populated areas.
Choosing the right technology is not just about performance – it is about responsibility.
