CEB has built an indoor power substation in Rodrigues

To increase reliability and embrace modern practices, the CEB is planning to construct a Gas-Insulated Substation (GIS) type substations. Previous CEB substations are Air-Insulated Substation (AIS) types which use atmospheric air insulation. A GIS uses a superior dielectric gas, SF6, at moderate pressure for insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are housed in SF6 gas metal enclosures. GIS substations will be constructed at the following locations in the coming years: 

  1. FUEL
  2. AML - including the laying of 66kV Underground Cables from Union Vale 
  3. Wooton 
  4. Ebène 
  5. L'Avenir 
  6. Administrative City, etc
