Equipped for any application.
Data centers, HPC clusters, and server farms require maximum availability. The same applies to power plants, energy storage systems, and grid stability equipment.
We reliably distribute energy for grid operators, industrial facilities, and municipal utilities – from local substations to plant networks, and from manufacturing to heavy industry.
Windparks, Photovoltaikanlagen und Ladeinfrastruktur laufen bei uns robust im Dauerbetrieb, auch unter wechselnden Umgebungsbedingungen.
Wind farms, photovoltaic systems, and charging infrastructure operate robustly in continuous service with us, even under changing environmental conditions.

We build without SF6 – not because the law requires it, but because it’s the better technology.
Two proven technologies for every application: air-insulated or fluid-insulated with MIDEL 7131.
No system leaves our factory until it has been 100% tested.
Developed and manufactured at our own facilities in Moosburg and Eisleben.

We’ve been developing switchgear in Germany since 1909 – at our facilities in Moosburg and Eisleben. For us, building SF6-free switchgear isn’t just a trend – it’s a living tradition.
As of January 1, 2026, new medium-voltage systems up to 24 kV may no longer be put into service using the climate-damaging insulating gas SF6. Starting in 2030, the ban will also apply to systems up to 52 kV, and starting in 2035, only recycled SF6 may be used for maintenance. For grid operators, municipal utilities, and industrial companies, this means: Those investing now should opt for SF6-free technology right away – not as a stopgap measure, but as a secure long-term choice. Driescher has been building its medium-voltage systems SF6-free, with air or fluid insulation, for decades – not just since the law went into effect.
Not every substation has the same amount of space or the same requirements. Air-insulated systems have been the proven choice for many standard applications for decades. Where space is particularly limited—such as in existing substations or during retrofits – fluid-insulated, unpressurized systems stand out thanks to their compact design. Both technologies are SF6-free as standard at Driescher, but differ in space requirements, design, and areas of application. The best way to determine which solution fits your project is to discuss it together – just contact us.
Out with the old switchgear, in with the new – without having to remodel the substation: In retrofit projects, space is often the limiting factor. Compact, unpressurized systems make it possible to modernize even cramped existing substations where other solutions reach their limits. This allows for the replacement of outdated or SF6-containing systems without requiring any changes to the substation itself.
The appropriate voltage level depends on your grid and your application. A local power grid for general electricity supply typically operates at 12 or 24 kV, while larger industrial facilities or transfer substations more often require 36 kV. Driescher covers all three ranges, so you’ll find what you need with us regardless of your voltage level. The easiest way is to briefly describe your project to us, and we’ll tell you which solution is right for you.
Yes, and we’ve been doing so long before it became a legal requirement. Depending on the series, we use either air or a fluid-insulated, unpressurized design as the insulating medium. SF6 is not used in any of our systems. For us, this isn’t a reaction to new regulations, but rather the result of decades of experience in switchgear manufacturing.
As of January 1, 2026, new medium-voltage systems up to 24 kV may no longer be put into service using SF6. Starting in 2030, this ban will also apply to systems up to 52 kV, and starting in 2035, only recycled SF6 may be used for maintenance work. Anyone planning a new system now can avoid having to retrofit it later and can opt for an SF6-free solution right from the start. We’d be happy to advise you on which option makes the most sense for your project.
Air-insulated systems simply use air as the insulating medium. This is a proven, robust technology that has been performing reliably in the field for many decades. Fluid-insulated systems, on the other hand, use a biodegradable insulating fluid, allowing them to be built in a particularly compact and pressureless design – a major advantage, especially when space is limited. Which of the two designs is right for your project depends primarily on the available space and the installation site, and that’s exactly what we’d love to discuss with you.
In many cases, yes. Our compact series are designed specifically for situations where space is limited and an old system needs to be replaced without making any changes to the building itself. This is particularly evident in retrofit projects in older substations. It’s best if we take a look at your specific on-site conditions together; then we can tell you exactly which solution is right for you.
For our unpressurized series, which are designed to be arc-flash-safe, an additional building safety assessment or pressure relief analysis for the substation is generally not required. This not only saves time but often reduces planning costs as well. However, since there may be differences depending on the design and installation situation, we prefer to clarify the details in a personal conversation with you.
Delivery time depends heavily on the selected system type and the specific configuration – for example, the desired secondary technology or project-specific adaptations. General estimates are rarely helpful in this context. It’s best to contact us directly so we can provide you with a reliable estimate for your specific project.
Our systems are designed for long operating times and are intentionally low-maintenance so that you don’t have to constantly worry about them during operation. Before a system leaves our factory, it is also 100% tested for functionality and safety. This takes time during production, but gives you, the operator, exactly the peace of mind that matters most in medium-voltage technology.
Our medium-voltage systems are developed in Germany, at our locations in Moosburg and Eisleben. There, our engineers have been working for many years on switchgear that must function reliably in everyday use, and it is precisely this expertise that goes into every new system. Construction then takes place at three of our own facilities, allowing us to maintain full control over every step of the manufacturing process.
