PFISTERER Sicon Connectors
Did you know that PFISTERER invented hexagonal pressing in the 1950s?
The Pfisterer Sicon range offers reliable and durable connections for all conductors.
The security of supply of energy networks is based on reliable and lasting contacts.
They are the key to secure power transmission. At the same time, assembly should be as simple as possible and risks of error should be largely excluded. For contacting cable ends, there are two methods recognized in practice with pressing and screwdriving technology, which have proven themselves. Pfisterer as a contact technology specialist offers a complete program for both processes.
Press Connection – Proven & Known
With the invention of the six-edge pressing technology in the 1950s, Pfisterer set a standard that is still used today. There is a reason for this. The six-edge press connection is simple, fast and reliable. Prerequisites for assembly success are the exact assignment of sleeve, conductor and the right tool. In track construction and industrial series production, pressing technology impresses with its cost efficiency.

Screw Connection – Universal & Simple
With the development of the SICON bolted connector, Pfisterer set new standards for easy handling and safety. Each connector covers a wide clamping range and is suitable for all types of socket. The patented ‘stepless’ shear bolt guarantees ideal contact for each specific conductor and helps the engineer to feel confident in the success of his installation.
SICON is always the right choice particularly suited to single connections, small series, and maintenance work.
Pfisterer also provides innovative solutions for connections and branches. Thanks to the 2DIREKT transformer terminal, you have a simple, universal, and space-saving way to connect distribution transformers. The patented tap-off ISICOMPACT terminal establishes all contacts for a 4-conductor cable branch using a single screw connection. And the PLUG system is a plug-in high-voltage connection for modern trains, wind power plants, industrial applications, and more.
A SICON Replaces 98 Press Connectors
Compared to the pressing technology, SICON connectors bring a significantly reduced variety of variants. The 1:1 assignment of conductor and sleeve is no longer necessary and with our eight standard variants, fitters on the construction site are equipped for all eventualities. This reduces warehousing and transport costs enormously. SICON connectors are mounted with a standard rattle with hexagonal bit – pressing tools are superfluous.
Pfisterer
The Pfisterer corporate group has been dealing with the interfaces in the flow of electricity ever since it was founded back in 1921.
As a specialist in energy transmission and distribution, Pfisterer offer our customers and business partners a range of sophisticated, future-ready products: For all voltage ranges and wherever reliable, long-lasting systems are needed for powerful energy grids.
As well as the energy sector, they are also active in transport technology and industrial solutions.
SICON SHEARBOLT CONNECTORS
The Right Connection for All LV MV HV Conductors – For years, bolted clamps, connectors, and cable lugs have been gaining ground – with good reason. Bolted connectors offer technical and practical advantages that compression technology cannot match.
Bolt type connectors offer not only technical, but also practical advantages over compression technology. All SICON Shearbolt Cable Connectors cover a wide conductor cross-section range so that you always have the right connectors on site for any application.
Main benefits of Sicon Connectors include:
- Reliable connection for all conductors
- Optimal contact force for all conductors
- No damage to individual strands
- Installation with standard tools
- Ideal for all type of joints or terminations
- Wide application range
