Abstract
The invention discloses a fabrication method for an aluminium alloy cable. Aluminium alloy consists of the following elements in percentage by weight: 0.1 to 0.5 percent of Co, 0.06 to 0.5 percent of Si, 0.05 to 0.1 percent of Sc, 0.02 to 0.3 percent of Zr, 0 to 0.05 percent of Ce and the balance of aluminium and inevitable impurities. The fabrication method includes the following steps: after the elements are proportioned and cast, the following steps of heat treatment are carried out: solution treatment is carried out under the temperature of 480 DEG C to 510 DEG C; aging treatment is then carried out under the temperature of 155 DEG C to 245 DEG C for 8 to 12 hours; a wire with the diameter of 0.5mm to 3mm is then drawn under the temperature of 80 DEG C to 120 DEG C, and the electric conductivity and mechanical properties of the aluminium alloy cable are effectively enhanced.
Description
Technical field
The present invention relates to a kind of manufacturing approach of cable, especially relate to a kind of manufacturing approach of aluminium alloy cable.
Background technology
In field of power transmission, aluminium light weight, inexpensive, and conductivity is better, specific strength is high, mar proof is good, thereby occupy superiority at electrical field.At transmission line, especially on supertension line and the big span line, the aluminium alloy electric cable is the material of main part of power transmission cable line always.In short supply along with the copper resource is the electric wire Development Trend with aluminium for copper, and the aluminium alloy conductor core with multi-functional characteristic is the inevitable requirement of electric wire development.
The many structural designs of prior art from wire rod, and seldom focus on to go design from the composition of wire rod, for directly using the various aluminium alloy cables of prior art.As the manufacturing approach of cable, its performance does not reach optimization.
Simultaneously, for every kind of aluminium alloy cable, though all will be through Overheating Treatment; But because the difference of metallic element, and the difference of lattice energy, the heat treatment method of every kind of electric wire; All directly have influence on the microstructure of alloy, and then influence the electric conductivity and the mechanical performance of alloy.
