Aerial Bundled Conductors (ABC)

Overview

Aerial Bundled Conductors (ABC), also known as aerial bundled cables, are an advanced overhead power distribution solution utilizing several insulated phase conductors bundled tightly together, typically accompanied by a bare neutral conductor. Unlike traditional bare-wire networks that rely on wide air gaps for separation, ABC systems bring the insulated lines into direct contact, saving valuable spatial footprint. This configuration offers higher safety and reliability, significantly lowers power transmission losses, and improves stability in voltage regulation. By reducing upfront installation overhead alongside long-term maintenance and operation costs, ABC lines deliver ultimate system economy for modern utility grids.
