ENERGY TRANSMISSION

YEO provides turnkey construction services covering engineering, procurement, construction, erection, testing, and commissioning processes in a wide range of Air Insulated Switchgear (AIS) or Gas Insulated Switchgear (GIS) high voltage substations and transmission lines from 110kV to 500kV.

High voltage substations are facilities located at the connection points between generation – transmission – distribution networks in the power transmission chain from power plants to consumers. These centers can act as a step-up substation by raising the electrical voltage or as a step-down substation by lowering the electrical voltage.

Substations consist of primary equipment such as power transformers, breakers, disconnectors, current-voltage transformers, surge arresters, and secondary equipment such as protection & control relays, SCADA Systems, RTU and communication systems, AC/DC panels, and control buildings.

Substations are large and complex structures. A reliable substation depends on the quality of the primary and secondary equipment, starting from proper engineering and project management, to effective site management and installation quality. YEO has a great experience for different voltage levels and busbar types of the countries. The busbar types YEO has experienced so far are mentioned below.
