Bourg-en-Bresse Factory

2June 18th, 2008

The Bourg factory, established in 1956, has two core businesses :

- The manufacturing of insulated cables from 6 to 132 kV

- The manufacturing of bare overhead lines and earthing conductors

It is organised in two manufacturing halls :

- Conductors

- Cables
