Description (excerpt):

This overview contains information about electric transmission lines which are installed underground, rather than overhead on poles or towers. Underground cables have different technical requirements than overhead lines and have different environmental impacts. Due to their different physical, environmental, and construction needs, underground transmission generally costs more and may be more complicated to construct than overhead lines. Issues discussed in this pamphlet include:
 Types of Underground Electric Transmission Cables
 Ancillary Facilities
 Construction and Operation Considerations
 Costs
 Repairs
