Conductors, connectors, and hardware operating at high temperatures

The trend in most utilities today is to increase the capacity of their transmission lines wherever practical. It has become increasingly difficult to build new lines because of increased costs to obtain rights of way, public intervention, and state licensing requirements. These obstacles have significantly increased the cost and lead times required to place new lines into service. The lost revenue opportunities from power purchase/sale agreements with other systems because of limited transmission facilities can be substantial. Therefore, utilities are attempting to get as much capacity as is practical from the addition of new high capacity lines or modifying existing lines for high temperature operation.
