Manufacturing method of 6101BT7 aluminum alloy thick-walled pipe conductors for electrical power equipment

The invention belongs to the technical field of aluminum alloy materials for electrical power equipment, particularly relates to a manufacturing method of high-strength and high-conductivity aluminum alloy thick-walled pipe conductors for high-voltage-resistant electrical power equipment for an inner hole to pass through a high-voltage wire, and in particular relates to a manufacturing method of 6101BT7 phi 146*11 mm (suitable for 6101BT7 pipes in various specifications) aluminum alloy thick-walled pipe conductors. A used aluminum alloy ingot comprises the following elements in percentage by mass: 0.40-0.55% of Si, 0.15-0.25% of Fe, less than or equal to 0.05% of Cu, less than or equal to 0.05% of Mn, 0.40-0.55% of Mg, less than or equal to 0.10% of Zn, less than or equal to 0.02% of Cr, less than or equal to 0.03% of single impurities, less than or equal to 0.10% of total impurities, and the balance of Al. According to the invention, problems such as mass production and delivery can be effectively solved, me
