Underground cables have been employed in a range of situations to assist power project developers to overcome local problems. For example, shielded underground cables carry power through urban areas where overhead lines would be technically unfeasible or an unacceptable intrusion. In some cases, the hidden nature of cables has protected areas of outstanding natural beauty, such as the Vale of York in the UK or the Gudena Valley in Denmark. In other cases, cables have been substituted for overhead lines in order to allow new developments to work properly, such as at the new Madrid Airport.
View the following case studies for specific examples of where cables have been used effectively.
