What are the advantages of hollow conductors?

Hollow conductors offer several advantages. First, they reduce the conductor's own weight-a crucial factor in applications with strict weight requirements, such as overhead power lines. Second, the hollow structure enhances heat dissipation, allowing heat generated during power transmission to escape more efficiently; this, in turn, increases the conductor's current-carrying capacity and extends its service life. Third, hollow conductors generally offer greater flexibility than solid ones, making them easier to bend and install, which reduces both construction difficulty and costs. Fourth, hollow conductors provide certain electromagnetic benefits, helping to minimize electromagnetic interference and eddy-current losses.
