11 kV Elevated Substation
Elevated substations are typically built above the ground. Elevated substations often have enhanced safety features such as fencing, surveillance system and motorized gate to prevent unauthorized access and ensure secure operations. The 11kV Elevated main intake substation is normally fed from 132/11kV primary substation inside the same compound. In elevated substations, the raised floor is used for the installation of control and relay panels.
The Elevated Substation project covers a turnkey job including design and engineering, Civil works, manufacturing of equipment, Installation, testing & Commissioning until the full operation of Substation. Al -Ahleia switchgear Co. have executed many 11kV Elevated main intake substations for Kwait Oil & Gas Company.
Major Equipment’s in the 11kV Elevated main intake substations
11kV Double busbar switchgear.
Duplex control and relay panel
