Abstract

High-Temperature Low-Sag (HTLS) conductors, such as Aluminum Conductor Composite Core (ACCC), improve infrastructure to support the delivery of power to meet the nation's increasing demand for electricity. Their response to low-velocity impacts during transportation, installation or in service, however, has not been addressed in the past. Therefore, this study investigates both experimentally and numerically mechanical effects associated with transverse low-velocity impacts on energy dissipation by the conductors subjected to either free or constrained end conditions and large axial tensile loads. Impact experiments were conducted using a newly designed and manufactured testing apparatus. The experimental work was strongly supported by non-linear static and dynamic finite element analysis. It has been determined that ACCC exhibited very good resistance to impact under constrained end conditions with and without axial tension. It was also identified that the most damaging condition to the conductors under impact is the free end situation when conductors were allowed to develop severe bending.
