This is a medium-voltage (MV) Aerial Bundled Cable (ABC) designed for overhead power distribution, built to the AS/NZS 3599.1 standard. Its construction is defined by its materials: AL (aluminum conductor), XLPE (insulation), CWS (copper wire screen), and HDPE (sheath). The cable features a screened design for higher voltage applications, with three insulated cores bundled around a galvanized steel support wire.
