High-conductivity and heat-resistant aluminum wire and its production process are characterized by multiple high-strength or extra-high-strength steel wires with tensile strength ≥ 1560 MPa twisted into steel strands as the load-bearing core wire, and the outer circumference is stranded with a conductivity greater than The 62% IACS high-conductivity and heat-resistant aluminum round wire and aluminum profiled wire are made of electrical conductors. The load-bearing steel core wire is pre-stressed and has low creep and extremely high strength characteristics. The electrical conductors are heat-treated at no more than 400°C. It has heat-resistant properties and satisfies the effect that the residual strength after heating at 230°C for 1 hour is greater than 95%. As a transmission line, it can withstand long-term operation at a high temperature of 150°C. It has excellent high conductivity and good sag characteristics. It is suitable for new transmission lines and old transmission lines for capacity expansion and transformation. Its significant advantages are high conductivity, high temperature resistance, and arc It has good sag characteristics, less damage to the transmission line, smooth surface, and strong resistance to wind vibration and freezing rain and snow disasters.

High-conductivity and heat-resistant aluminum wire

The production process of high-conductivity and heat-resistant aluminum wire is characterized by the following production steps:

•  a. Aluminum rods with aluminum content ≥ 99.75% are drawn into aluminum round single wires with a circular cross-sectional shape and an S-shaped, or Z-shaped, or T-shaped, or C-shaped cross-sectional shape. Shaped aluminum single wire;
•  b. The above-mentioned aluminum single wire is heat-treated at no more than 400° C. to make it have heat-resistant properties and meet the effect that the residual strength after heating at 230° C. for 1 hour is greater than 95%.
