Description

technical field

[0001] The invention relates to the field of aluminum alloy materials, in particular to an aluminum alloy conductor material with high compression resistance and creep resistance and low resistivity, a preparation method thereof and a cable. Background technique

[0002] In current-carrying conductors, aluminum alloy conductors are prone to deformation as the temperature of cables and joints changes over time. This deformation is a slow plastic deformation that occurs over time under a compressive stress state, which is called compression creep. Since the compression creep of common aluminum alloy conductors is much higher than that of copper, it will increase the resistance value at the joint, which may cause the risk of sparking at the joint. However, the compressive creep resistance and electrical conductivity of aluminum alloy conductors often cannot be taken into account at the same time. How to adjust the formula to develop an aluminum alloy conductor ...
