Low-velocity impact to transmission line conductors

Despite their geometrical simplicity, the numerical models provided useful information regarding the response of the conductor to both static and dynamic conditions. Most importantly it has been determined that the PCCC exhibits good resistance to impact under constrained end conditions with and without initial axial tension. It was also identified that the most damaging condition under impact is when the conductor had free ends and was thus subjected to severe bending. It has been shown in this work that the suggested approach to the impact testing of transmission lines could result in useful predictions of their structural integrity after low-velocity impact either during installation or in service.
