Embodiment Construction

[0033] A self-damping, low-loss, high-corrosion hard aluminum type wire stranded wire, see figure 1 : It includes an inner core and an outer stranded layer. The outer stranded layer specifically includes an inner layer conductor and an outer layer conductor. The inner core is specifically a load-bearing reinforcement core formed by concentrically twisting zinc-5% aluminum-mixed coated steel wires. A layer of inner conductor layer consisting of N strands of 63% IACS conductive circular cross-section aluminum wire strands 12 is concentrically and tightly stranded outside the load-bearing reinforcing core, and at least one layer is concentrically stranded on the inner conductor layer and consists of several 63 %IACS Conductivity "SZ" type cross-section aluminum wire strands 13 closed outer conductor layer.

[0034] When the outer layer conductor is one layer, the twist direction of the outer layer conductor of a single layer is right, and the twist direction of the adjacent inner...

Abstract

The invention provides a self-damping low-loss high-corrosion-resistant hard aluminum wire strand, which improves the anti-corrosion performance of the wire, reduces the breeze vibration of the wire,reduces the line loss and effectively increases the line distance under the condition that the overall outer diameter of the wire is not changed, the wind load of the wire is not increased, and the transmission capacity is not reduced. The wire strand comprises an inner core and an outer stranding layer, wherein the outer stranding layer comprises an inner layer conductor, an outer layer conductor, and the inner core is zinc-5% aluminum- load-bearing reinforce core formed by concentric strand of mixed plated steel wire, At least one close out conductor layer consist of a plurality of 63% IACSconductivity SZ-type cross-sectional aluminum wire strands is concentrically stranded on the inner conductor lay, and the inner conductor layer comprises N stranded 63% IACS conductivity circular cross-sectional aluminum wire strands.

Description

technical field [0001] The invention relates to the technical field of cable structures, specifically a self-damping, low-loss, and high-corrosion duralumin-shaped twisted wire, and the invention also provides a manufacture of a self-damping, low-loss, and high-corrosion duralumin-shaped twisted wire method. Background technique [0002] With the sustained and rapid development of my country's national economy, the differentiated requirements for power transmission capacity and power transmission equipment are becoming more and more obvious. At present, the construction of the global transmission network is continuously strengthened, the Three Gorges transmission project line is continuously extended, the west-to-east power transmission, the north-south mutual supply, and the national network. Along with the construction of new lines, old lines that have been in operation for many years are also facing line replacement and transformation. Therefore, the demand for new cond...
