ASTM Covered Aerial Medium Voltage Covered Conductor (Spacer Cable Or Tree Wire)
Spacer Cable Or Tree Wire ApplicationCovered Aerial MV Cable – Installed with other Covered Aerial MV cables and a supporting messenger through a series of space- maintaining devices (spacers). The resulting close-proximity configuration minimizes the amount of space and hardware required for line installation, particularly useful in congested areas.
Tree Wire – Used for spans where trees crowd the right-of-way, such as in wooded residential areas, when a minimum of interference with the environment is desired. Covering minimizes power outages due to conductor contact with tree limbs, reducing the need for frequent or severe trimming.
Spacer Cable – Installed with other spacer cables and a supporting messenger through a series of space-maintaining devices (spacers). The resulting close-proximity configuration minimizes the amount of space and hardware required for line installation; particularly useful in congested areas.
