The "Outdoor Cable Trench Layout" drawing is the one of the most important drawing of the EHV Substations. This drawing shows the route of the Power & Control cables coming to Switchgear, Control & Relay panels, etc. from outdoor Switchyard or from the Dead End Tower of a Transmission Line.

In the trench the cables will be laid on MS Racks or GS Cable Trays with proper tie arrangement. The outdoor Power & Control cable estimation is done on the basis of this layout.

Due to Climate change and International pressure, Renewable energy power plants are fast replacing conventional thermal power plants (coal or gas or oil fired). The most common type of renewable energy power plants are either Solar or Wind turbines. The power generated in these power plants gets interconnected / synchronised with the electricity grid through Extra high voltage Switchyards and Transmission lines. The existing Grid substation may also need extension of its EHV bays to accommodate termination of the Transmission line originated from the Solar / Wind farm substation. Satcon provides the following Consultancy services for the power system interconnection :

1. Visit to the existing Grid substation and checking feasibility of the proposed interconnection with the solar / wind power plant.
