CABLE ACCESSORIES FOR POWER GRIDS
PFISTERER has a proven track record of providing high-performance products to ensure that high-voltage and extra-high-voltage grids can be successfully established with plastic-insulated cables:
- dry and oil-insulated outdoor cable terminations for the transition from cables to bare conductors or systems
- a variety of connection sleeves for all EHV/HV cables and various locations
- link boxes for all common earthing and cross-bonding types plus other accessories
RETROFIT – SIMPLE, SUSTAINABLE MODERNIZATION
The service life of terminations is often shorter than that of their higher-level systems. Anyone making clever use of existing properties for overdue modernization and for far-sighted restructuring are better off – and for a long time. We have the solution to this challenge – with our dry-insulated terminations.
CABLE SYSTEMS WITH PFISTERER COMPONENTS
PFISTERER technologies and design variants have proven themselves worldwide. When we plan and implement turnkey underground cable systems, our expertise shines through. We develop them made-to-measure according to customer specifications.
CONSTRUCTION AND REPAIR SOLUTIONS – VERSITALE BYPASSES FOR AL SCENARIOS
There can be many factors behind system failure. PFISTERER offers a powerful way to counter this – with individually designed modular cable systems. Each of them can be used quickly, flexibly and safely as a reliable bypass. In the event of sudden failures, they allow an immediate response and uninterrupted operation when it comes to long-planned work.
Training and installation
for safe commissioning
High voltage places the highest demands on the safety and reliability of systems and their connective components and accessories. Quality is important, but it’s not the only factor. Professional installation is equally important. We ensure both – and have our high-voltage components installed exclusively by specialist personnel whom we have trained and certified for this specific product.
Overhead lines
Armed against ALL CHALLENGES
Overhead lines transport electricity over long distances - and they have a lot of work to do when it comes to the increasing global demand. In order to do what they are supposed to do, advanced technologies and materials are required for the efficient transmission of electricity. PFISTERER knows what is needed. And PFISTERER delivers it. We are a global partner in systems and components for overhead line projects – in the extreme heat of the tropics and deserts, in coastal regions and in northern latitudes with their extremely low temperatures.

KEEPING TOGETHER WHAT NEEDS TO WORK TOGETHER
INDIVIDUAL CHAIN DESIGNS
We supply complete insulator chains - and not just standardized, but also tailored and manufactured precisely to the individual requirements of our customers on request. No matter how complex it may be, there is no compromise on reliability. We test our chains carefully in the laboratory and they have proven themselves in the field.
COMPACT LINES
Modern overhead lines have a compact design. This has both functional and aesthetic reasons. Their visual appearance is becoming increasingly important. Our innovative insulator chain designs mean you can completely rethink overhead line projects.
SIMULATIONS AND TESTS
- Electric and mechanical simulations
- Electric and mechanical tests
- Analytical damping studies
IN-HOUSE ENGINEERING AND TEST FIELDS
We have our own engineering and testing facilities. That is a huge advantage, as it ensures that we can quickly put innovative technological ideas into practice while maintaining the highest quality standards. Both are reflected in the reliability and efficiency of our projects.
SILICONE INSULATORS
We have an extensive range of insulators. It includes long-rod, suspension and support insulators for AC and DC applications, with a load capacity of up to 1,000 kN and voltages of up to 1,000 kV. First class is our aspiration, because we want to meet the highest demands. And we achieve this thanks to high-quality injection molding technologies and modular production.
Advantages of silicone insulators:
- They are hydrophobic and self-cleaning.
- They are lightweight and shock-resistant.
- They are easy to install and require little maintenance.
- They are less prone to vandalism.
INSULATOR FITTINGS
We offer a wide range of customized insulator fittings that comply with various standards such as DIN VDE, IEC and ANSI.
FITTINGS FOR OVERHEAD LINE CHAINS AND CONDUCTOR CABLES
Our fittings withstand mechanical and electrical loads, interact optimally with conductors and insulators, are corrosion-resistant and easy to install.
WARNING SPHERES
Our warning spheres made of pigmented polyamide or polyethylene are available in a variety of designs and colors. What sets them apart:
- They are UV and ozone resistant.
- They have a reliable metal clamping system.
- They can be used on OPGW and ground cables.
DAMPING SYSTEMS
In studies, we simulate how overhead lines act with and without a damping system. And we assess which is the optimum damping system. With our Stockbridge dampers, we ensure effective and reliable control of aluminum vibrations. Our spacer dampers offer effective protection for conductor bundles.
MEASURING VIBRATIONS ON CONDUCTOR CABLES
Our vibration recorders measure aeolian vibrations and partial voltage oscillations in the field. The software for assessing and graphically displaying the data is included in the package. The devices are available for hire or purchase.

Safety TECHNOLOGY
“Better safe than sorry” particularly applies in safety technology across all voltage levels. This is because safety technology is one of the most sensitive areas in energy supply. Operation needs to be correspondingly simple and unambiguous. And of course, the same applies here in particular: reliability is vital. Our products – voltage detectors, earthing and short-circuiting devices, earthing and actuating rods or duration test systems – meet these conditions with precision for every requirement.
Substations
Variety of components in
a modular system
Substations are central nodes in electricity grids – and are therefore key to the energy supply. If operators want to ensure that transformers and gas-insulated switchgear are safe and economical, they should first ensure that their connection components and accessories are working efficiently and reliably. PFISTERER’s technologies combine advanced technology and component diversity in a modular system – for a grid connection and system protection that operators can rely on.

systems for sensitive areas
The global population is growing, along with cities in particular. Growing urbanization increases the need for high-voltage systems, while at the same time space for them is limited. High safety requirements pose an additional challenge. Our connection system addresses both of these issues – and enables GIS and transformers to be optimally designed for urban areas, both technically and economically.
Variable systems for
efficient operation and testing
If transformers and GIS need to be tested, this can also be done with our technology in a flexible way. Effort and risk are reduced to a minimum. And of course: The plug-in components can be easily combined with other tried and tested high-voltage fittings from PFISTERER.
