Manufacture method of high electric superalloy conductor and product thereof

Abstract

The invention discloses a preparing method of high-conductive thermal tolerance aluminum alloy wire, which comprises the following steps: 1. adding Zr and Fe in the electric aluminium liquid (0.3-0.6% Zr, 0.10-0.25 Fe, not more than 0.08% Si, not more than 0.01% element sum of Ti, V, Mn and Cr); 2. manufacturing thermal tolerance aluminium alloy rod material through continuous aluminium casting manufacturing line; 3. setting the heading temperature at 400-430 deg.c for 50h; 4. drawing and stranding to manufacture high-conductive thermal tolerance alloy wire.

Description

Technical field [0001] The invention relates to a method for manufacturing an aluminum alloy wire, in particular to a method for manufacturing a high-conductivity super-heat-resistant aluminum alloy wire used in overhead power transmission and transformation lines and products produced by the method. Background technique [0002] At present, the heat-resistant wires used in my country's urban and rural power transmission and transformation lines are generally twisted from ordinary heat-resistant aluminum alloy single wires and ordinary galvanized steel wires. The aluminum alloy wire generally has a long-term operating temperature of no more than 150°C, which can only increase the carrying capacity by 1.6 times compared with ordinary wires, and the increase in capacity is not large. However, the ordinary galvanized steel wire used as a strengthening element has a large linear expansion coefficient after preheating, and the transmission capacity After the increase, the temperatu...

[0002] At present, the heat-resistant wires used in my country's urban and rural power transmission and transformation lines are generally twisted from ordinary heat-resistant aluminum alloy single wires and ordinary galvanized steel wires. The aluminum alloy wire generally has a long-term operating temperature of no more than 150°C, which can only increase the carrying capacity by 1.6 times compared with ordinary wires, and the increase in capacity is not large. However, the ordinary galvanized steel wire used as a strengthening element has a large linear expansion coefficient after preheating, and the transmission capacity After the increase, the temperature of the wire rises and the sag increases, which affects the safe operation of the line
