3-Layer 25kV AAC Tree Wire/Spacer Cable
An Alternative and Robust Design to Bare AAC Conductors to Harden the Electrical Grids.
3-Layer 25kV AAC Tree Wire Concentrically Stranded AAC Track-Resistant Crosslinked Polyethylene.
- Conductor:Concentrically stranded AAC
- 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.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.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.
