TRACES OF TIME

Independence, innovation, reliability and quality - over the decades, these four 
pillars have made PFISTERER what we are today: a leading global technology company for systems solutions and components in power generation, power transmission and power distribution.

The evidence of our future viability runs like a continuous thread through the past.

A NEW CHAPTER

For 102 years, PFISTERER has been inextricably linked to the Pfisterer family. More than half of this time with Karl-Heinz Pfisterer, grandson of the founder and currently Honorary Chairman of the Supervisory Board. Together with Prof. Wolfgang Blättchen – who has supported the company with experience and foresight as Chairman of the Supervisory Board since the mid-2010s – he played a decisive role in shaping the transformation of PFISTERER into a European stock corporation. This transformation laid the foundations for a long-term, independent and successful future for the company. We look ahead with enthusiasm and confidence – and look back with pride.

  • PFISTERER is planning to build a new high-voltage test laboratory to shorten innovation cycles and expand testing capacity.
  • At the open day in Winterbach, citizens had the opportunity to take a look behind the scenes and experience our contribution to the global power transition.
  • PFISTERER plans to reduce Scope 1 and Scope 2 CO2 emissions by 90 percent by 2029 compared to 2020.
  • By establishing a new site in Saudi Arabia, we are doing our part to supply energy to an economically growing region.
  • PFISTERER positions itself for a successful long-term future. In future, the PFISTERER holding company will operate as a listed European company, an SE. 
  • New locations established in Asia and North America. PFISTERER thus optimizes its international availability, bringing greater sustainability to logistics and distribution. At the same time, PFISTERER invests heavily in the latest laboratory and testing technology. 
  • The Dutch electricity grid operator TenneT commissions PFISTERER to develop the world's first plug-in, universally applicable submarine cable repair joint up to 170 kV.
  • PFISTERER celebrates its 100th birthday. 
  • The sale of the LAPP Insulators ceramics division and the Rail business unit sets a new course for the PFISTERER Group. The clear focus is on the core expertise in the areas of components and systems for high-voltage overhead lines and underground cable networks based on the materials of silicone and metal. 
  • PFISTERER builds a new sales and technology center in Küssnacht am Rigi, Switzerland, combining its two Swiss sites in Malters and Altdorf. 
  • PFISTERER triggers investment in digitalization, technology and transformation.
  • The first completely dry-insulated, self-supporting DOC cable termination is created as the next evolutionary stage in environmentally friendly and time-saving solutions.
  • PFISTERER expands its horizons towards the Middle East and forms a new company in Dubai for sales, assembly and training.
  • The Swiss subsidiaries PFISTERER SEFAG AG and PFISTERER Ixosil AG merge into PFISTERER Switzerland AG.
  • With FrontCon, PFISTERER is the first supplier to solve the problem of labor-intensive and time-consuming single-wire insulated cable contacting. FrontCon cuts assembly times by around 80 per cent. This is recognized by the Golden Amper Award.
  • PFISTERER develops a voltage tester for HVDC applications.
  • A new production site is added in Kadaň, Czech Republic – and with it one of the most modern silicone-processing production facilities in the world.
  • PFISTERER takes over LAPP Insulators and gains a leading position in the global market for high-voltage insulators.
  • Oil and gas-free, plug-in high-voltage cable joints for environmentally conscious cable connections are created.
  • Together with the architecture and design firm Bystrup, PFISTERER develops a design for aesthetically pleasing and future-oriented high-voltage pylons for the Danish energy supplier ENERGIENET, producing long rod insulators more than four meters long. The low height of the masts and their award-winning industrial design increase acceptance among the public.
  • PFISTERER launches oil and gas-free cable terminations on the market. 
  • TENSOREX, a spring-based tensioning system for electric contact lines, is the latest innovation. PFISTERER revolutionizes the technology for keeping railroad conductor cables taut.
  • Energy suppliers are delighted. PFISTERER releases ISICOMPACT, the successor to the SCK junction box that has connected millions of homes to the power grid – and live, with just a single bolt, safely and quickly.
  • PFISTERER becomes an offshore pioneer through its collaboration with Q7 in the Netherlands. It is just the first of many other offshore wind farm (OWF) projects. PFISTERER is also involved in the first German OWF Alpha Ventus (2009), the first commercial German OWF Global Tech 1 (2012), the first modern 66 kV OWF East Anglia One (2020) and the first commercial OWF in the USA Vineyard Wind 1 (2023), for example.
  • PFISTERER combines its business areas in four international centers of expertise: cable systems (Winterbach/Germany), components (Gussenstadt/Germany), overhead line systems (Malters/Switzerland) and contact line systems (Barcelona/Spain).
  • With the unique SICON screw connector, PFISTERER breaks new ground in user-friendly, fast and safe assembly. The stepless shear bolt is now used in numerous battery storage systems, solar power plants and electric charging stations.
  • PFISTERER relocates its company headquarters to Winterbach in Swabia, Germany, where the Group is still based today.
  • PFISTERER develops plug-in bushings for high-voltage systems, thus expanding its CONNEX portfolio. Bare high-voltage conductors can now be connected to transformers with an unprecedented degree of flexibility.
  • In close collaboration with EOS Holding Lausanne, PFISTERER develops the first 420 kV compact line with silicone composite insulators. It will pave the way for all subsequent compact cables with insulating crossbars.
  • PLUG is created, a plug-in connection system for high-current applications that is firmly established in wind turbines, solar parks, trains and machines.
  • PFISTERER redesigns its Gussenstadt plant, achieving significantly more efficient production as a result.
  • The CONNEX product family gets an attractive addition. PFISTERER patents plug-in surge arresters.
  • PFISTERER develops innovative silicone-based overhead line insulators. The material stands out with its hydrophobic, self-cleaning properties and is also lighter and more robust than the widely used insulating medium of porcelain. The innovation attracts international attention in the electrical industry and is now in use worldwide.
  • PFISTERER Holding is founded.
  • Karl-Heinz Pfisterer takes over the management of the company as CEO and partner. He later moves to the Supervisory Board.
  • For the first time, PFISTERER presents its CONNEX connection system, which is set to revolutionize the industry. With the dry-insulated, plug-in inner cone technology, cables, transformers and switchgear can be connected plug and play, similar to the plug and socket principle, but on a much larger scale. CONNEX is a game changer that facilitates unique emergency concepts and temporary solutions for grid modification, revision, maintenance and testing, among other things.

  • No one has ever thought of anything like this: the PK hinged cleats for equipping workstations make renowned industrial companies such as Daimler and Bosch enthusiastic customers.
  • Karl Pfisterer founds his “Factory for specialty electrical products” in Stuttgart-Untertürkheim at the age of 41. His goal: to improve the world of electricity transmission with solutions for all aspects of energy grid interfaces. The path: independence, innovative strength, reliability and quality. Karl Pfisterer’s pioneering spirit is still with us to this day.
