Our medium-voltage product families at a glance
GEMIS® – The modular air-insulated medium-voltage switchgear
Our GEMIS® systems are metal-encapsulated, air-insulated medium-voltage systems for voltages up to 24 kV. They offer the highest possible operating availability, ergonomic operability and modular flexibility in field configuration.
Versions:
- GEMIS® 12 / 24 kV – Standard Configurations with Circuit Breakers
- GEMIS® double busbar – for increased network flexibility
- GEMIS® 24/20 – particularly compact, with fixed mounting and switch disconnector
Technical Highlights:
- Rated voltage: 12–24 kV
- Rated current: up to 2500 A
- Surge current resistance: up to 31.5 kA (3s)
- Degree of protection: IP4X
- Arc Qualification: IAC FLR 25–31.5 kA, 1s
- Operating Availability: LSC2b
GEMIS® Double Busbar – Ideal for Operation
If you need to supply a large number of load centers with high power requirements safely and stably, you can rely on the GEMIS® with double busbar. It offers you exceptional network flexibility and of course also meets all standard standards necessary for safe and standard-compliant operation, such as sprinkler and arc fault tests.
GEMIS® 24/20 – Compact and high-performance system for local substations
The newly developed system concept based on IEC 62271-200 is particularly characterized by its space-saving design, which nevertheless offers maximum flexibility. We deliver the GEMIS® 24/20 to you ready for use and adapted to your needs – low-maintenance and, of course, with a high level of Personal safety and operational availability.
GENIMOD® – For combined low- and medium-voltage solutions
While GEMIS® covers the medium-voltage range, the GENIMOD® system allows the combination with motor control centers (MCC) and low-voltage switchgear. Ideal for companies that need an end-to-end energy solution – from 400 V to 24 kV.
Technically well thought-out – modular design
Our medium-voltage switchboards typically consist of:
- Busbar room
- Pressure relief channel (optionally equipped)
- Low-voltage chamber (optionally variably equipped)
- Circuit breaker or switch disconnector room
- Cable connection room – easy to install & prepared for all cable systems
The modular design allows for flexible field sequence and easy later expansions without compromising operational reliability. Our service team will be happy to help you with this. For more information on the construction method, please contact us or request our current brochure free of charge.
