GIS Modernization
AREVA T&D has a solution for aging GIS switchgear: an individualized industrial modernization alternative for switchgear with 20 years or more of active service.
Our solution extends GIS lifetime by adapting new circuit breakers and accessories, and effectively uprating when requested. Our GIS life-extension program is your best means to avoiding unnecessary replacement.
 
Avoiding complete shutdown and major civil work modifi­cations, our GIS Modernization Concept helps customers choose the best solution for each specific situation.
Based on the age and equipment state, AREVA T&D engineers design a ‘retrofit’ operation that can extend your total equipment lifetime up to +45 years.
Additional upgrades are available, such as:

  • Advanced monitoring device compatibility
  • Full renovation of SF6 tightness
  • Renovation of disconnectors and earthing switch mechanisms
  • Accessory renovation or replacement (bursting discs, filling valves, moisture absorbers,…)

Our GIS Modernization Concept is the most ecological solution: SF6 quantity can be reduced by as much as 30% and this modernization produces less industrial waste.
