An 11-year field test of 3M Aluminum Conductor Composite Reinforced (“ACCR”), in cooperation with Hawaii Electric Company, on a 46-kV distribution line on the island of Oahu has confirmed the salt ...
Core samples of the ACCR conductor showed no sign of tensile strength loss, with results ranging from 108 percent to 110 percent of rated breaking strength. While the conductor was still in the air, ...
Thermal sag is often responsible for causing grid outages on electrical transmission and distribution (T&D) lines. It happens when the current running through an electrical conductor cable exceeds the ...
