Abstract

The invention discloses a power transmission line carbon fiber composite core lead core rod, and belongs to the technical field of power transmission line leads. The power transmission line carbon fiber composite core lead core rod is prepared from the following raw materials in parts by weight: 30-40 parts of modified carbon fibers, 12-20 parts of glass fibers, 6-12 parts of polyester fibers, 8-15 parts of silicon nitride, 20-28 parts of polyurethane resin, 205-210 parts of xylene, 15-22 parts of epoxy resin, 5.5-10 parts of curing agent and 1.2-2 parts of surfactant. The surface of the corerod is round, clean and smooth and consistent in color and luster without defect, the tensile strength is over 2663MPa and the elastic modulus is over 130GPa. The core rod can be wound on a 55D-diameter cylinder at a winding speed of not more than 3r / min for one circle and the core rod does not crack or break, the withstand pressure of not less than 30KN in the radial pressure resistance test andthe end part does not crack or peel. The tensile strength of the surface layer is over 2511MPa after the torsion test for 360 degrees, and the surface layer does not crack.

Description

technical field [0001] The invention relates to the technical field of transmission line conductors, in particular to a carbon fiber composite core conductor mandrel for transmission lines. Background technique [0002] The transmission wire is the main component of the overhead line. It is responsible for the transmission of electric energy from the power source to the power load center, and occupies an extremely important position in the transmission line. In the process of national development, the development of the power system has become a major event, and the shortage of power supply has become a major problem that needs to be solved urgently. The shortage of power resources has brought about the long-term insufficient power consumption of enterprises and individuals, and the backward construction of transmission lines has led to insufficient distribution of power resources, which cannot be operated rationally, resulting in waste of resources, and is also one of the f...
