Bare Conductor

Definition: A bare conductor is an electrical conductor, typically made of metal like copper or aluminum, that is not covered with insulation or any protective coating. It is used to carry electrical current and is often found in overhead power lines, busbars, or grounding systems where insulation is not required due to the design or environment. Bare conductors are exposed to the elements and rely on air or spacing to prevent unintended contact or short circuits.

No Insulation: A bare conductor has no insulating layer, meaning it is directly exposed to the environment. It is typically made of materials like aluminum or copper.

Usage: Commonly used in overhead power lines where insulation is not required (e.g., transmission lines supported by poles or towers) since air acts as a natural insulator.

Definition: A covered conductor is a metal wire, usually copper or aluminum, coated with a thin insulating layer to reduce the risk of short circuits, corrosion, or contact with external objects. Unlike fully insulated cables, it isn't rated for full voltage but offers added protection in overhead power lines.

Insulated Layer: A covered conductor has a thin protective coating or insulation (not as thick as insulated cables) to prevent short circuits in case of accidental contact.

Usage: Often used in areas with limited space or higher risk of contact (e.g., tree-prone regions or urban distribution lines), providing better safety than bare conductors but less insulation than fully insulated cables.
