| ABB builds underground substations in Qatar Swiss engineering group ABB has won an order worth around $30 million from the Qatar General Electricity and Water Corporation (Kahramaa), the electricity and water operator in Qatar, to build two underground substations to help meet increasing residential and commercial demand for power in the capital city of Doha. The substations will be practically invisible to the public and form part of the first phase of Musheireb, the key project of Dohaland, which is a subsidiary of the Qatar Foundation for education, science and community development. The Musheireb project will be executed in five stages and aims to reconstruct and restore a 35 hectare area in Doha's old city center. It will include an underground pedestrian area, car parks as well as historic and new buildings. ABB will design, supply, install and commission two 66 kV (kilovolt) gas-insulated switchgear (GIS) substations as well as transformers, 11 kV metal-clad air-insulated switchgear (AIS enclosed in a metal housing) and cables. The substations will be equipped with ABB automation systems and the latest generation of protection and control products, compliant with the IEC 61850 global substation communications standard. The project is scheduled for completion by the end of 2012. write your comments about the article :: © 2011 Construction News :: home page |
