Project Overview

400 KV Interconnection / ISOLUX Spain — Including three substations: Aleppo-W: New 400 KV conventional substation with 3 diameters, 2×300 MVA power transformers, and 20 KV capacitors. Hassakeh: New 400 KV Conventional substation with 2 diameters, 2×300 MVA power transformers. Dimas EXT: Extension of 400 KV conventional substation. Tishreen GIS II and Kodsaya S/S: Erection, installation & commissioning for complete GIS stations.

The Challenge

Coordinating the construction of multiple substations across different locations simultaneously while maintaining grid stability. Each substation had different technical requirements and site conditions, requiring careful planning and resource allocation.

Our Solution

We established dedicated project teams for each substation location, ensuring focused supervision and quality control. Our experienced engineers coordinated all civil and electrical works across all sites simultaneously, implementing rigorous quality control processes throughout.
