The easiest way to increase the transmission capacity is to increase the conductor cross-sectional area of the overhead transmission line, but this increases the weight and causes a problem that the allowable strength of the existing steel tower is exceeded.

れた導電用耐熱Ａｌ合金線材を得ている。Therefore, in order to increase the power transmission capacity without changing the conductor cross-sectional area, A having high heat resistance and high conductivity is used.
An alloy wire is used for the conductor. As an Al alloy satisfying these requirements, an Al—Zr alloy containing about 0.1 wt% of Zr has been used. This Al-Zr
In a system alloy, when the content of Zr is increased in order to improve heat resistance, on the contrary, the conductivity is lowered.
For this reason, the Al—Zr-based alloy contains Fe, M

(200 to 200 hours), which is inferior in productivity and raises the production cost. Therefore, A
By adding a small amount of Be as a third element to the l-Zr-based alloy, a heat-resistant Al alloy (Al-Zr-Be-based alloy) wire for electric conduction has been developed in which the heat treatment (aging treatment) time is shortened. The situation is applied to transmission lines.
