Covered Overhead Protection
Covered or aerial insulated construction reduces contact risk compared with bare overhead conductor routes.
Tree Wire
Tree Wire for protected overhead distribution and tree-contact risk reduction.
Tree Wire is used on overhead routes where an insulated or covered conductor surface is required to reduce contact risk and improve distribution line reliability.
Product Overview
Tree Wire should be selected according to the actual project route, not by product name alone. Before quotation, review voltage grade, core arrangement, messenger or neutral design, insulation system and utility standard. Datasheet wording, compliance documents and final supply notes should stay aligned with the selected standard and installation conditions.
Applications
- covered overhead distribution lines
- tree-contact or vegetation-sensitive routes
- urban and rural medium-voltage distribution upgrades
- overhead lines requiring additional insulation coverage
Construction
Aluminum or alloy conductor with weather-resistant insulation or covering. Thickness, voltage class, conductor size and covering material should be reviewed according to the selected overhead distribution standard.
Marking on Cable
FARWALK CABLE – Tree Wire – [standard] – [voltage] – [size] – [year] – [meter mark]
Cable Identification
- Core color or numbering can be reviewed according to utility practice.
- Outer insulation color and printing should follow the inquiry or project standard.
Standards
- IEC 60502-1 / IEC 60502-2
- BS 7870
- AS/NZS 3560.1 / AS/NZS 3599.1
- project utility requirements
Main Features
Tree and Urban Route Use
Suitable for distribution routes where vegetation, space limitation or contact protection must be considered.
Voltage and Covering Review
For Tree Wire, conductor material, insulation thickness and covering type should match voltage class and local utility practice.
Product Selection Guide
Voltage and Route
Separate LV ABC, MV ABC, service drop, covered conductor and tree wire before selecting construction.
Phase Arrangement
Confirm duplex, triplex, quadruplex, single-core or bundled configuration according to the service route.
Messenger / Neutral
Review messenger material, neutral conductor, full neutral or self-supporting design with the utility requirement.
Weather and Fittings
Check UV exposure, temperature, fittings, span length and local utility standard before final selection.
