Investigation of mechanical properties of single layer ACSR based on an Integrated Model

The design, selection and improvement for overhead aluminum conductor steel reinforced (ACSR) require intensive understanding of the cable characteristics. Until now, the analytical model for single layer ACSR is not satisfactory because of an unacceptable error between the analytical value and the experimental value. This paper presents a newly developed Integrated Model designed and performed on single layer conductors to investigate their electromagnetic, thermal and mechanical properties based on the Unified Model which was initially designed for three-layer ACSR. Carefully designed physical experiments to obtain conductor electromagnetic properties were used to validate the Integrated Model for various composite single layer ACSR: Guinea, Penguin, and Raven, popularly used in North America. An analysis of the electrical losses is also reported, and mechanical properties of odd-layer ACSR conductors are studied through case examples.
