Construction:

Conductor:Concentrically stranded ACSR (water or moisture block optional)
Strand Shield:Semi-conducting crosslinked polymer
Inner Layer:Low-Density Crosslinked Polyethylene (LDXLPE)
Outer Layer:Flame-Retardant High-Density Track-Resistant Crosslinked Polyethylene (FR-HDTRXLPE). Contains no lead and is naturally halogen-free. Gray or black in color.

Applications and Features:

This product is best suited for high fire risk areas including California, Arizona, and Canada. California has designated specific areas as high fire risk zones, classified into Fire Hazard Severity Zones (FHSZ) based on factors like vegetation, weather, and terrain.

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.
