ALPHA Elektrotechnik AG

Established over 90 years ago in Nidau, Switzerland, ALPHA Elektrotechnik Ltd is a company steeped in tradition.

Having started out in the power transmission business selling disconnectors for medium- and high-voltage networks, ALPHA-ET now also takes care of an independent business area — cable solutions — for the transfer of energy in the high-voltage networks of modern railways.

ALPHA-ET disconnectors have been used around the world for a number of decades and have proved to be very efficient under a wide range of conditions. Power transmission to high-speed trains works reliably and guarantees the safe operation of trains around the world. 

The reliability of the products and their safe application over many years are key hallmarks of their quality. Added to this is the outstanding level of service provided with the products by our long-serving employees, as well as on-site installation and training sessions.
