“…Methodology To predict the behavior of the single straight strand under tensile loads, the mathematical geometric model is further implemented in a finite element program. For this purpose ANSYS 14.0 [12] software is used. Generated 3D geometric models of the single straight strand and the results of the finite element elastic behavior analyses of the strand under tension loads are determined.…”

Wire ropes are considered and applied to industrial applications that includes mining, off-shore oil production, and towing or mooring ships. Wire ropes are also used extensively in such diverse transportation applications as ski-lifts, cable cars, bridges, cranes and elevators. Premature failure of ropes can be costly in any application. In mining, the human costs due to the premature failure of a rope can be devastating. The wire rope considered in present research is IS 398, ACSR Conductor, Theoretical calculations are performed to calculate sag and slack for the rope. Distance between poles is taken as considered 30480mm. Thermal elongation with temperature variation is calculated and also simulated and analyzed with ANSYS design software. Aeolian vibration frequency is calculated to obtain frequencies with different wind speed, Software results for frequencies are found similar to theoretically calculated results. Experimental analysis is performed in IIT Indore to conduct tensile. It is found that breaking load is approximately 28KN and software simulation results for tensile test are approx. 30KN. Present research ultimately tried to focus on the modeling and analysis of wire rope for transmission lines considering the pole distance and sag of the wire rope, further comparing the simulated results with the theoretical, and trying to make a common set up for the test and validation of results experimentally.

“…So broken steel strands in ACSR cables have a very strong impact on the safe operation of power grids. During the long-term outdoor fi eld service, ACSR cables may be damaged by lightning strike, atmospheric corrosion, ice-shedding, wind vibration of conductors, lines' galloping and external forces' destroy and so forth [1][2][3]. Much information is available on the short-and mid-term atmospheric corrosion of aluminium, in the form of corrosion data (mass loss and pit penetration) as a function of atmosphere type, corrosion mechanisms, environmental variables, surface orientation, etc.…”

“…Because of being operated in wild environments, ACSR conductors are usually subject to fretting damage by wind excitation and atmospheric corrosion by industrial pollution and salty environments. As a type of critical component of high-voltage transmission systems, most ACSR conductors have been operated for 30-45 years, approaching to their middle life, thereby requiring very high maintenance costs [1][2][3][4][5][6]. Therefore, it is significant to explore fretting damage behaviors of ACSR conductors in dry and corrosive conditions.…”

This work reports the fretting wear behavior of aluminum cable steel reinforced (ACSR) conductors for use in high-voltage transmission line. Fretting wear tests of Al wires were conducted on a servo-controlled fatigue testing machine with self-made assistant apparatus, and their fretting process characteristics, friction force, wear damage, and wear surface morphology were detailed analyzed. The results show that the running regime of Al wires changes from a gross slip regime to a mixed regime more quickly as increasing contact load. With increasing amplitudes, gross slip regimes are more dominant under contact loads of lower than 30 N. The maximum friction force is relatively smaller in the NaCl solution than in a dry friction environment. The primary wear mechanisms in dry friction environments are abrasive wear and adhesive wear whereas abrasive wear and fatigue damage are dominant in NaCl solution.
