Sound innovations at the cutting-edge of economic technology – this has been PFISTERER’s mission statement ever since it was founded. We turn prototypes into individual solutions and individual solutions into standard products. We use our experience to improve tried-and-tested technology for practical use. And when needed, we can even break brand new ground:
- Using new materials, such as silicone, PFISTERER is pioneering new forms of insulation. It is also using new plastic-metal combinations, like the material in the ISICOMPACT tap connector. Unlike purely metallic designs, they offer considerably more freedom in design and increase the ease of installation while maintaining the same level of contact quality.
- With new technology such as shear bolts with infinite adjustment for SICON connectors, dry high-voltage terminations, or the spring-based TENSOREX tensioning system for overhead lines.
- Also with brand new solutions, such as the dry, plug-in CONNEX surge arrestors for high-voltage applications or the PLUG system for low-voltage ranges.
- And with new, ground-breaking applications in energy technology, such as the intelligent CrossPower energy management system which can be used anywhere in the world.
1985: SILCOSIL insulators made from silicone for the first time

SILCOSIL insulators on high-voltage overhead lines prevent voltage surges between the tower and the power line. PFISTERER’s insulators are made from silicone, a material that is much less sensitive than the porcelain and glass used previously.
2000: New fields of application for PFISTERER

PFISTERER expands its area of focus to transport technology, new energy sources, and industrial applications. The PLUG low-voltage system used to transmit high currents in harsh environmental conditions is used in railway systems for the first time. These days, almost every new high-speed train in Europe is equipped with this system.
Sophisticated solutions for specific problems
PFISTERER uses cutting-edge computer-aided simulation models in its development process in order to assess the way new buildings behave. This enables us to produce the best possible prototypes, which we then subject to rigorous development tests. Instead of focusing on a standalone product during this process, we develop complex solutions for specific problems. And we always think about the long-term effects. After all, it often takes a long time for innovations to establish themselves in the safety-conscious energy sector. The fact that we set new industry standards with our ideas and shape international conventions makes our work even more satisfying.
