Underground high voltage cables are used when overhead lines are inappropriate or impractical to install in some locations in and around Wilmington. They not only are an effective alternative but they are also a justifiable solution for critical circumstances.
The superiority of underground high voltage cables in Wilmington, MA lies in their ability to reduce the visual impact in areas of natural beauty and to minimize potential health risks in areas close to communities and habitats. The increased security of supply has significantly lessened if not eliminated transmission losses and power disruptions resulting from extreme weather condition.
High voltage cables can be established underground with the use of modern technology. These underground cables are usually buried, installed in a tunnel, or contained in a concrete and covered trough. The number of UHVCs may double if a high capacity is required in the area.
Often underground high voltage cables are not preferred because the related costs are higher than that of overhead lines. However, the additional costs incurred can be offset by the use of less expensive XLPE cables which are insulated using plastic rather than oil. Also, the substantial benefits of less maintenance and repairs, and fewer power outages from the application of UHVCs can compensate for the over-and-above expenses
