Overhead conductor
WebOverhead Conductor Market size exceeded USD 665 million in 2024 and is projected to expand at more than 5% CAGR from 2024 to 2032. Rising electricity demand across the globe will spur industry expansion. The refurbishment and replacement of old grid infrastructure with new transmission lines, as well as the increasing installation of high ... The most common conductor in use for transmission today is aluminum conductor steel reinforced (ACSR). Also seeing much use is all-aluminum-alloy conductor (AAAC). Aluminum is used because it has about half the weight and lower cost of a comparable resistance copper cable. It does, however, require a larger diameter than copper because of lower specific conductivity. Copper was more popular in the past and is still in use, especially at lower voltage…
