In recent years

due to rapid development of national economy

the demand for electricity from various industries is gradually increased

and the construction of power grid infrastructure is constantly promoted. With the escalation of quantities of high-capacity

high-voltage

remote transmission line

there appear some problems in the running of ordinary steel-cored aluminum stranded wire. In order to meet the national power industry development requirements

it is urgently needed to prepare a new energy-saving conductor with large proportion of draw-weight

desirable sag performance

low energy loss and optimal corrosion resistance. Considering that the electrical conductivity of aluminum alloy can be improved by rare earth elements

the relationship among the material composition

technology and performance of a new rare earth aluminum alloy material was mainly introduced

which can provide reference for engineering application.
