Description & Challenges

This project was to install two double circuit 380kV Underground Cables circuits along with Fiber Optic Cables between

1. Makkah North 380kV BSP and Makkah Central 380kV BSP with an approximate route length 6.7km and
2. Makkah West 380kV BSP and Makkah Central 380kV BSP with an approximate route length 11.9km

Technical Specifications of this project demanded close interface coordination with various other substation and cable contractors to carry out the design. DAR with its competent and experienced team successfully carried out this job in a well-coordinated manner with all the stack holders and completed the project with a very good note as per client specified requirements.
