What Is Bare Conductor?

Bare conductor is a conductor that is not covered with an insulating layer. Conductors are generally made of copper, aluminum, aluminum alloy, steel and other materials. Bare wires are generally used for the erection of high-voltage lines in the field because they have no skin, which is conducive to heat dissipation. In order to increase the tensile strength, steel strand is placed in the center of some aluminum strands, which is called "steel cored aluminum wire". Bare conductors without insulating sheath have also caused many accidents in densely populated areas. In cities where conditions permit, insulated wires have been gradually used for overhead high-voltage lines or transferred to underground cables.
