Rail market

A global Chauvin Arnoux Group offering from Chauvin Arnoux®, Enerdis®, Pyrocontrole® and Manumesure for all measurement applications in the Rail sector

 

 

Ever since its foundation in 1893, CHAUVIN ARNOUX has constantly innovated in the field of electrical measuring instruments and electrical equipment, offering its customers all the flexibility and expertise which it has built up in electrical engineering and, more specifically, in the particularly demanding Rail sector.

Resolutely forward-looking, the CHAUVIN ARNOUX Group's products have proved their ability to adapt to the severe technical and environmental constraints imposed by the international standards regarding electrical safety to protect both people and property.

Today, more than ever, most of our products are manufactured in our French factories and on our international sites, with the same attention to compliance with the product quality and environmental standards. Enerdis equipment is used in the traction chain, the power electronics and the command-control systems: relays, temperature probes, panel meters, etc.

In the tertiary installations, supply stations, substations, workshops and maintenance centres, Chauvin Arnoux's products and equipment are used to measure the electrical parameters of the installations. Alongside this, Manumesure, the Group's metrology subsidiary, proposes a a wide range of services for calibration and monitoring of instrument fleets through its network of agencies all over France.

This know-how has been exported worldwide, as the Group's products are found in the metros in Cairo, Mexico City and Caracas, to give just a few examples.
