SPEC 84021
3-Layer 25kV ACSR Tree Wire/Spacer Cable
An Alternative and Robust Design to Bare ACSR Conductors to Harden the Electrical Grids.
3-Layer 25kV ACSR Tree Wire Concentrically Stranded ACSR Track-Resistant Crosslinked Polyethylene.
Construction:
- Conductor:Concentrically stranded ACSR
- Strand Shield:Semi-conducting cross linked polymer
- Inner Layer:Low-Density Crosslinked Polyethylene (LDXLPE)
- Outer Layer:High-Density Track-Resistant Crosslinked Polyethylene
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. Covering Rated 90°C Normal and 130°C Emergency Operation. Unless adequate knowledge of the thermal characteristics of the environment is known, the permissible conductor temperature should be reduced by 10°C or in accordance with available data.
