PFISTERER – Overhead Line and Cable Accessories for Low, Medium, High and Extra High Voltage

Contacting high-current conductors, insulating high voltages – that's our business since 1921. At all voltage levels and for all applications where high power must be transmitted reliably for decades.

These are our fields of applications:

overhead lines

Overhead Lines - silicone insulators, insulator sets and vibration damping

PFISTERER designs and delivers both individual components and complete insulator sets up to 1000 kV on the basis of silicone composite insulators. We can rely on 90 years of experience in the design of the systems and use modern simulation models for electrical field characteristics and mechanical loads.

We have the best conditions for the efficient development of complex custom solutions such as space-saving insulated cross-arms or upgrading existing overhead line systems. Our range of services also includes cable vibration damping - from computer simulation to data acquisition using instruments specifically developed for this purpose, right through to implementation with the help of damping elements.

Cable Systems - dry, dry pluggable and conventional cable accessories

cable jointsPFISTERER cable accessories are available for almost all types of plastic-insulated cables up to 550 kV. IXOSIL cable terminations are available using conventional oil-filled and modern dry slide-on technology. In the self-supporting version used with pylons, they can be pre-installed on the ground. IXOSIL cable joints using proven slip-on technology can be installed in no time, giving maximum operational reliability.

The dry pluggable CONNEX system is touch-proof, maintenance free, suitable for outdoor use and submersible. Using gas-insulated CONNEX joints, pluggable cable branches can even be produced. The installation of high voltage components requires extensive know-how and care. Our specialists have both, installing our sets for you anywhere in the world.

Substations - dry pluggable transformer and GIS connections, cable accessories, voltage detection and grounding equipment

connex systemPFISTERER products ensure low-loss, maintenance-free and long-lasting connections across the whole transmission chain. The dry pluggable CONNEX system makes power transformers completely pluggable. Touch-proof CONNEX cable connectors on both the upper and lower voltage side combined with the CONNEX solid surge arresters mean that enclosed stations are very compact.

For connections in the open air, pluggable bushings are also available. MV-CONNEX multiple cable connectors provide very compact and completely maintenance-free connections to the distribution network. In outdoor substations, IXOSIL cable terminations and outdoor switchgear terminals connect the individual components, while silicon supporting insulators provide the required insulation. For installation and maintenance we provide voltage detectors and customer specific ready assembled grounding and short-circuiting sets.

Energy distribution - compression and bolted connectors, voltage detection and grounding equipment

SICON screw connectors for medium voltage cables have some unique advantages, thanks to their state of the art technology. Optimal contact force, irrespective of conductor material, assembly without special tools and without any protrusions on the connector body. 2DIREKT transformer terminals reduce the number of transition points and thus the power dissipation and sources of faults. For underground distribution networks, we offer ISICOMPACT, the most compact and easiest to install branch connection in the world. For this we provide the ideal installation tools for the job together with voltage detectors and customer specific ready-assembled grounding and short-circuiting sets.

Railway Catenary Systems - connectors, insulators, tensioning devices, voltage detection and grounding equipment

PFISTERER offers a complete range of approved components: TENSOREX, the spring-operated tensioning system, silicone composite insulators, terminals and custom made droppers using screw or press technology, installation tools and voltage testers plus grounding and short-circuiting sets.

Industrial Applications - pluggable connectors

pluggable connectorsThe quicker you can replace drive components such as motors or power converters, the lower the downtime and the costs. Using the pluggable PLUG connection system you can create the ideal conditions for this. It produces clearly defined system boundaries and allows complex systems to be built using a modular and preassembled type of construction.

Renewable Energy - offshore certified cable accessories

In offshore substations for wind farms, complex technology must be fitted into a confined space. The CONNEX connector system for medium, high and extra high voltage cables is ideal for this application as it is touch-proof, compact, maintenance-free and resistant to salt water. So far it is the only system certified by Germanischer Lloyd for use offshore.

This technology has proven to be just as useful in the often extremely cramped conditions in substations of hydropower plants. When it comes to wind turbines on land or at sea, preassembled modules are needed, made possible by the PLUG high-current connector system. And with our easy to install medium and low-voltage connectors, small and medium sized onshore plants can be connected up efficiently.
