Substations supporting challenges faced by the grid - Linxon· For Example: Linxon has commissioned a 400-kV Gas-Insulated Switchgear (GIS) substation at Mohammed bin Rashid Al Maktoum (MBR) Solar Park in Dubai and also constructing Shams 400 kV Substation to support the flow of power from MBR Solar park to Dubai Electricity & Water Authority (DEWA) Grid. Shams substation will be commissioned by end of 2020.
CEB: GIS SUBSTATION 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.
