[Abstract]:There are differences in structure and physical characteristics between carbon fiber composite core wire (ACCC) and common steel core aluminum strand. The research results of carbon fiber composite conductor in connection and construction can be widely used in the line construction project of using carbon fiber composite core wire as overhead conductor, which has practical significance and economic benefit. Based on the "220 kV Xibaipoo-Pingshan double Circuit Line Compatibilization Project", aiming at the carbon fiber composite core conductor ACCC-600 / 71, the mechanical properties of the composite core wire are tested in this paper. Further research has been done on the tension release of composite core conductors and the life evaluation of composite core conductors. The main contents are as follows:. Based on the experience of gripping force test for many years, the paper compares the compression process of carbon fiber composite wire with that of traditional steel core aluminum strand, and analyzes some factors that affect the wire holding force. The grip strength test of carbon fiber composite conductor is introduced in detail, including test equipment, test requirements and results. 1) combining with the experience of gripping force test for many years, the compression bonding technology of carbon fiber composite wire and traditional steel core aluminum strand is compared. Some factors affecting the grip strength of the conductor are analyzed, and the grip strength test of the carbon fiber composite core wire is introduced in detail, including the test equipment, the test requirements and the results. 2) according to the characteristics of carbon fiber composite conductor, the special construction technology and key technology in tension laying line construction of this project are analyzed and verified, and the corresponding countermeasures are provided. Based on the wind vibration fatigue failure of transmission lines, combined with the low sag characteristics of carbon fiber composite core conductors and the stress of overhead conductors, the calculation method of conductor fatigue life is analyzed, and the fatigue life of transmission lines is preliminarily discussed.
