ClearComparison of Structural, Microstructural, Elastic, and Microplastic Properties of the AAAC (A50) and ACSR (AC50/8) Cables after Various Operation Periods in Power Transmission Lines
This study compared the structural and mechanical properties of aluminum cables used in overhead power transmission lines after different periods of operation. Both all-aluminum alloy and aluminum-steel reinforced cable types were tested for hardness, elastic modulus, and microstructural changes with age. Understanding cable degradation is important for maintaining safe and reliable electrical infrastructure.
Modification of the Structural, Microstructural, and Elastoplastic Properties of Aluminum Wires after Operation
Structural and microstructural changes in aluminum wires from overhead power transmission lines of 0 to 62 years service life were characterized using X-ray diffraction and electron backscatter diffraction, finding progressive work hardening and grain boundary changes that affect wire strength and longevity.
