Reference projects

At the PFISTERER group we are proud of our work, products, and the steadily growing number of satisfied customers. We would like to use this opportunity to introduce to you a selection of successful ventures and pioneering projects that were accomplished utilizing PFISTERER's products and services.

PFISTERER developed the first universal cable repair system suitable for all XLPE-insulated cables – regardless of type and cross-section – for Schleswig-Holstein Netz AG, the largest electricity network operator in the German state of Schleswig-Holstein and partner to some 900 municipalities.

PFISTERER is supplying French transmission system operator Réseau de Transport d’Électricité (RTE) with silicone composite insulators including protective fittings for suspension and strain strings with 225 kV and 400 kV and load classes from 150 kN to 600 kN.

This project is unique worldwide. DolWin gamma is one of the first and largest commercial offshore converter stations in the German North Sea. As part of the DolWin network connection project, it has been connected to another platform via a bridge system, using a new kind of flexible high-voltage cable with a conductor cross-section of 800 mm².

Just 36 hours from installation to switch-on – New York’s first mobile emergency transformer went online in record time. PFISTERER was involved from the outset in planning this new type of transformer, and supplied the dry pluggable CONNEX connection technology that forms a key element of the integrated solution.

With lush vegetation and an abundance of tropical flowers, the island of Kauai is one of the eight main Hawaiian islands and a unique natural paradise in the middle of the Pacific. Its isolated location is both a blessing and a challenge – particularly for local energy supplier KUIC.

The new power transformers from AVU Netz GmbH are universal in their application. This network operator in western Germany is already implementing three connection versions using identically constructed transformers and thus remaining flexible for future demands. This is made possible by the versatile CONNEX connection system.

To reduce vibrations caused by the wind, you don’t just need to know how, you also need to know where. That is because damping systems are only really effective if they are installed in the right place. A task for PFISTERER’s unique vibration recorder.

An aesthetic appearance: To meet this criterion for overhead lines in Denmark, PFISTERER developed four-meter-long composite insulators for truly beautiful energy.

Space-saving, innovative, underground. The Oerlikon substation uses intelligent, vertical connection technology by PFISTERER to free up building space.

When designing the Klus substation, personal safety was given number one priority because quick maintenance means maximum reliability, just as you would expect in Switzerland. CONNEX also reduces costs, just as you would expect from PFISTERER.

It’s all down to asking the right questions. How do the overhead line specialists at PFISTERER develop and test basic models for the power grids of the future?

Kraftwerke Oberhasli AG (KWO), a Swiss energy supplier, runs some of the most powerful hydropower plants in Europe but some of the plants have started to show their age. For the upgrades, the operators relied on PFISTERER technology.
