The Pfisterer group of companies is a global manufacturer of high-voltage cable accessories and system provider in the field of energy infrastructure. Around 2,700 employees develop, produce and sell components and complete solutions for all interfaces in the areas of low voltage, medium voltage , high voltage and extra high voltage . The products for all voltage levels from 110 V to 1,100 kV are among others. a. Used in power grids , offshore wind turbines , overhead lines for electric railways, overhead lines and as connection and connection components in industrial drives. The German-Swiss family company, to which Lapp Insulators also belongs, is represented in 18 countries.
history
From the company's foundation to 1945
In 1921, Karl Pfisterer founded the "Karl Pfisterer, factory for electrical engineering special items" in Stuttgart . The first company headquarters was in the Untertürkheim district on Kelterstrasse. During this time of electrification , difficulties arose again and again with metal connecting elements of conductors. The trained electrician Karl Pfisterer concentrated on this problem and developed an improved power fitting. The demand for Pfisterer fittings increased steadily. The company grew to 54 employees by 1927 and moved to Augsburger Straße 375, the company's headquarters for the next 60 years.
In 1937, Karl Pfisterer expanded his business area to include high-voltage overhead line fittings and switchgear terminal technology . He had a tension clamp for steel-aluminum ropes protected by patent. In addition, Karl Pfisterer developed the non-ferrous metal forging technology and acquired the first testing machines for his own development tests.
In 1940 the company took on the legal form of a KG . The company's founder, Karl Pfisterer, died in 1942. His son, Walter Pfisterer, continued his father's work as a personally liable partner and sole managing director. During one of the air raids on Stuttgart on December 9, 1944, the production facility in Stuttgart-Untertürkheim was completely destroyed.
From the post-war period until today
The company was rebuilt in the 1950s . In 1954 a new factory was completed on Inselstrasse in Stuttgart-Untertürkheim. The first foreign branch was established in 1957 with the SEFAG company in Malters , Switzerland . The entry into the large-scale use of plastics began in 1962 with the new plant in Winterbach . In 1968 Pfisterer invented the compact screw terminal, which from the late 1960s became the technical standard for all new buildings in Germany when it comes to connecting to underground power grids. A year later, Pfisterer received the patent for compact switching strips for low-voltage distribution and used them in the plastic distribution cabinets, which were new for the time.
In 1971, Karl-Heinz Pfisterer, Walter Pfisterer's son, was the third generation of the family to join the company. Pfisterer increased its commitment abroad in the 1970s . The international reputation in overhead line construction led to an extraordinary order: Pfisterer developed and manufactured special connecting elements to join the elements of the glass roof in the Munich Olympic Stadium . In 1975, in the year of the company's 50th anniversary, Pfisterer received the patent for the Connex cable connection system for medium-voltage applications. This made it possible to set up medium-voltage connections with factory-tested components in a modular manner.
Pfisterer Holding AG was founded in Winterbach in 1986. After a restructuring, the headquarters of the main administration was relocated in Stuttgart-Untertürkheim, the parts production in Gussenstadt and the assembly in Winterbach. New fields of application were added in 2000. Pfisterer expanded its activities to include traffic engineering, new energies and industrial applications. The plug low-voltage system, which transmits high currents in adverse environmental conditions, was used for the first time in rail technology.
In 2001 Pfisterer gave up the location in Stuttgart-Untertürkheim and relocated the company headquarters to Winterbach . In 2004, the Pfisterer group concentrated its business areas in the four national lines , overhead line systems ( Malters / Switzerland ) and contact line systems ( Barcelona / Spain ).
In 2015, Pfisterer launched the comprehensive “Next Level” investment and growth program. As part of this, a new production site is being built in Kádan, Czech Republic. With the acquisition of Lapp Insulators , one of the largest suppliers of high-voltage insulators made of porcelain and composite materials , the group of companies achieved a leading position on the world market for high-voltage insulators. The hybrid energy system Crosspower, newly developed by Pfisterer, was also used in practice for the first time in 2015. The intelligent management system balances the different power generation from wind turbines , solar cells and diesel generators and thus enables a reliable, decentralized power supply from renewable sources.
Corporate structure
In addition to the company's headquarters in Winterbach, the Pfisterer Group operates production facilities in Europe , North and South America and South Africa, as well as sales offices in 18 countries in Europe , Asia , Africa , South America and the USA . The company is still 100 percent owned by the Pfisterer family. Karl-Heinz Pfisterer is a member of the company's supervisory board .
