About the project
Design and replacement of existing 132 kV LPOF underground cables with new 132 kV, 3 x 1C x 1200 mm² copper XLPE cable, single cable per phase, together with fibre optic cables.
Scope of work
SDEC carried out the base and detailed design for the Saudi Electricity Company's replacement of existing 132 kV low-pressure oil-filled (LPOF) underground cables in Riyadh with new 132 kV XLPE cables - 3 x 1C x 1200 mm² copper, one cable per phase in flat formation - laid together with fibre optic cables. The design covered the cable route, ampacity, short-circuit and induced-voltage calculations, the sheath bonding scheme, link and joint box details, trench, duct bank and HDD sections, the fibre optic system, and the required modifications to the protection system.
