MV-CONNEX – Top-class technology from the inventor of the inner cone system
In 1975, PFISTERER showcased the first ever plug-in connection for mid-voltage cables. Back then it was a revolution, these days its the norm. And we literally mean the norm, as the EN 50180/EN 50181 standards are based on the CONNEX system by PFISTERER. Nowadays, the MV-CONNEX is still the benchmark for medium voltage cables. Ultimate safety, maximum power, and an unbeatably wide range of designs and special solutions are the hallmarks of the system. In addition to the traditional socket-plug combination, there are a number of smart system extensions for special applications.
Everything in one: The CONNEX multiple transformer connection for up to four cables
The multiple elbow bushing is installed on the mid-voltage side of the power transformer, instead of the standard porcelain bushings. This allows power to be distributed in the simplest way possible in a completely touch-proof system. As a result, bulky terminal boxes are now a thing of the past.
Plug-in motor connections reduce downtimes
High-performance motors can be connected and replaced within a short space of time thanks to the CMA CONNEX motor connection. As CONNEX solutions tend to come with full encapsulation, the terminal boxes normally needed are no longer required. The connection is also available in an ATEX design for use in areas at risk of explosions.
MV-CONNEX bus couplings for GIS
With busbar couplings, you can create simple module-based SF6 gas-insulated switchgears and even expand them on site because the gas chamber no longer needs to be opened for installation. The portfolio includes variants from 24 kV to 42 kV.
CONNEX surge arresters from 6 kV to 52 kV
CONNEX surge arresters are used to protect metal-enclosed switchgears and transformers. The surge arrester is attached directly to the switchgear and prevents excessively high levels of overvoltage from penetrating the system. The surge arresters are particularly effective at restricting overvoltage generated by reflected traveling waves and switching surges.
