Problems solved by technology

The aluminum alloy core aluminum stranded wire adopts LHA1 or LHA2 type aluminum-magnesium-silicon alloy round wire stranded wire core as the strengthening core. Since the tensile strength of the aluminum-magnesium-silicon alloy round wire is 295MPa-325Mpam, it is required for the design of overhead lines , the cross-section of the reinforcing core needs to be very large, which increases the cost of materials and production and installation. The biggest disadvantage is that the ratio of tension to weight is reduced at the same time.
The all-aluminum alloy wire is directly stranded by HA1 or HA2 type aluminum-magnesium-silicon alloy round wire without a reinforcing core, but the maximum conductivity of the aluminum-magnesium-silicon alloy round wire is only 53% IACS, so the wire High energy consumption, uneconomical

Description

Technical field [0001] The invention belongs to the technical field of wire design and production for transmission line engineering, and in particular relates to a method for manufacturing an ultra-high-strength aluminum alloy core overhead wire and an aluminum alloy core. Background technique [0002] Existing overhead wires are classified according to the materials of the structure, and are mainly divided into two types: the reinforced core and the conductor have the same material, and the reinforced core and the conductor have different materials. [0003] Overhead wires with different reinforcing cores and conductors are mainly divided into overhead wires with galvanized steel strands as the reinforcing core and overhead wires with a carbon fiber composite core as the reinforcing core. The wire with galvanized steel stranded wire as the reinforcing core is susceptible to corrosion due to the different electrode potentials of the galvanized steel wire and the outer aluminum stra...
