High-strength heat-resistant aluminium alloy pipe type generatrix

Abstract

The invention relates to a high strength heat-resistant aluminum alloy tubular bus, in particular to a tubular bus used for distribution device of high-voltage and supervoltage power transmission and transformation. The invention is characterized in that the tubular bus is made of Al-Mg-Si-ZrO3 alloy, the composition of the alloy: Si 0.30 to 0.50, Fe 0.35, Cu 0.10, Mn0.10, Mg 0.50 to 0.75, Cr 0.10, Zn0.10, Ti 0.10 and Zr 0.20 to 0.30; impurity is less than or equal to 1.5; the rest is Al. The invention has the advantages that the alloy recrystallization temperature is increased by 80 to 100 degrees since Zr is added in Al-Mg-Si alloy, enabling high working temperature of tubular bus up to 200 DEG C; the heat-resistant performance and current capacity of the bus as well as safety and reliability of the transmission and transformation system are improved, while the line loss during power transmission is reduced; the requirements on high-voltage and supervoltage power transmission and transformation can be met due to high strength, good conductivity, stable mechanical property and high current capacity at high temperature and ability to keep mechanical property of conductor in case of transient short circuit; the alloy used for the tubular bus can be used to produce other conductor material.

AI Technical Summary

Benefits of technology

This patented technology uses an addition made from specific elements called zirconium (zinc) into certain types of alloys that are commonly found throughout modern materials like iron or steel. These new compositions have improved thermal stability compared to traditional methods for producing these metals while also having better electrical characteristics than older ones due to their higher melting point and lower resistive value. Additionally, they provide longer lifespan when subjected to sudden changes in temperatures above 250°C without losing their effectiveness over time. Overall, this innovation enhances the performance and efficiency of electricity transport systems such as cables, transformers, switchgear devices, etc., making them more reliable and efficient during operation under harsh conditions.
