Demand for power continues to increase at an alarming rate, forcing utilities to put greater and greater electrical loads on their existing lines. However, most existing transmission circuits have been designed for operation at or below 93˚C. Aluminum Conductor Steel Reinforced (ACSR), the most commonly used conductor, cannot handle the higher temperatures resulting from increased current loads. With the increasing de-regulation pressures, rising construction costs and right-of-way scarcity, another option is needed.
