Substation Focused on Environmental Design

One of the important trends in design of new overhead lines over the past 20 years has been development of structures and designs that are less obtrusive and more pleasing visually. Much the same process has also been going on at substations. For example, even 25 years ago, efforts had already been in place as far afield as Finland and Australia to build substations designed to facilitate acceptance by affected communities – either through aesthetic...
