Aluminum Covered Line Wire Application
Aluminum Covered Line Wire is designed for use on overhead secondary distribution lines. Covered Line Wire is not an electrically insulated conductor and is treated as a bare conductor when installed. The insulation provides protection against circuit interruption due to weather.
