Description:

Tree wire or covered open wire consists of the conductor (aluminum, aluminum alloy or ACSR ) and the extruded covering (conductor shield, low density inner layer and protective outer layer). Covering thickness depends on the system voltage. It is designed for full span applications and is supported on polyethylene insulators. We also offer a two layer covered conductor design for 15kV systems that are not subject to heavy tree contact. Covered conductors are available in black or gray depending on visual preference.

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 flash overs 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 – 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.

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.

Benefits:

Covering prevents faults due to contact

Proprietary, high density outer layer resists abrasion, electrical tracking and UV degradation.

Reduced NESC phase spacing is possible due to high impulse strength covering.

Pole hardware is the same as bare wire construction except that Hendrix polyethylene insulators are required.

Application:

Qingzhou Cable provides tree wire designed for systems from 15kV through 46kV. Polyethylene insulators must be used to insure dielectric compatibility with conductor covering. Conductors are supported on crossarms or standoff brackets. Span lengths are limited by the conductor breaking strength and the amount of sag that is permissible. Covered conductors are rated for continuous operation at 75°C. (Consult sales representative for 46kV tree wire systems).
