- Abstract:
- An accurate understanding of the stress distribution of each layer of ACSR in the temperature field can provide theoretical basis for the safety design and fatigue analysis of overhead conductors . Based on the properties of ACSR materials and its collaborative deformation characteristics, the relationship between stress and temperature of wire strands is studied by theoretical analysis and finite element simulation. And the effects of average temperature and radial temperature difference on the stress of outermost aluminum strands of aluminum strand decreased with the increase of temperature. While the stress of steel core increase with the increase of temperature; when the radial temperature difference was considered, the outer aluminum strand stress increased with the increase of temperature fifference, and steel core aluminum strand internal stress decreased with the increase of temperature difference. When the temperature reached 20ºc, the outer layer of aluminum stress increased about 49%.
