What Is Bare Cable?

Bare cable is an uninsulated electrical conductor installed on transmission towers or utility poles, where air provides natural insulation. Compared with insulated cables, bare cable offers lower weight, better heat dissipation, and lower installation costs.

AACSR bare cable consists of 6201 aluminum alloy strands wrapped around a high-strength galvanized steel core, providing greater tensile strength than standard ACSR while maintaining excellent current-carrying capacity.
