Established over 80 years ago in Nidau, Switzerland, ALPHA Elektrotechnik AG is a company stepped in tradition. Starting out in the power transmission business selling disconnectors, ALPHA also has a separate business unit – „cable solutions“- for the transfer of energy in medium voltage systems of modern railways. In 1999 ALPHA started to develop and produce medium-voltage assemblies for railways (traction) from 3kV to 25kV. Thanks to our high level of quality and flexibility, ALPHA has an important number of international references in the railway sector.
The heart of the transmission process is the partially insulated or fully insulated pluggable jumper. Jumpers are car2car connections to ensure the distribution of energy between rail cars, particularly on commuter trains and high-speed trains. ALPHA masters one of the principal difficulties, which consists in reconciling flexibility and resistance in order to make it possible that the cable supports millions of torsion movements, resonance extreme climatic conditions. We are pleased to welcome you on the SWISSRAIL booth to tell you more about all products and services we offer.
