3-Layer 15kV AAAC Tree Wire/Spacer Cable

An Alternative and Robust Design to Bare AAAC Conductors to Harden the Electrical Grids.
3-Layer 15kV AAAC Tree Wire Concentrically Stranded AAAC Track-Resistant Crosslinked Polyethylene (HDTRXLPE).

...

Construction:

  1. Conductor:Aluminum-alloy 6201-T81 wires, concentrically stranded
  2. Strand Shield:Semi-conducting cross linked polymer
  3. Inner Layer:Low-Density Crosslinked Polyethylene (LDXLPE)
  4. Outer Layer:High-Density Track-Resistant Crosslinked Polyethylene (HDTRXLPE)

Applications and Features:

Used for primary and secondary overhead distribution where limited space is available or desired for rights-of-way. Installed the same as bare conductors, however, covering is effective in preventing direct shorts and instantaneous flashovers should tree limbs or other objects contact conductors in such close proximity.
  • 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.
  • Covered Aerial MV Cable (CAMV)/Spacer 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.
