Space-Saving Tree Wire 15kV/25kV/35kV - AAC/ACSR Conductor for Urban Power Lines

Product Overview

The 15kV/25kV/35kV Multi-Layer Tree Wire is a high-performance, space-efficient overhead distribution cable designed for congested urban and suburban environments. Engineered to minimize right-of-way requirements and prevent short circuits caused by tree contact, this uninsulated yet track-resistant covered conductor ensures reliable power delivery while reducing installation hardware and maintenance costs. Ideal for alleyways, tight corridors, and forested areas, it combines durability with compliance to ASTM and ICEA standards.

Key Features

  • Voltage Ratings: 15kV, 25kV, or 35kV for primary and secondary distribution.

  • Track-Resistant Covering: High-Density Polyethylene (HDPE) or Crosslinked Polyethylene (XLPE) prevents flashovers and direct shorts.

  • Compact Design: Concentrically stranded conductors (AAC, AAAC, ACSR) minimize space requirements.

  • Environmental Resilience: Resists tree abrasion, UV radiation, and extreme weather.

  • Optional Strand Shield: Enhanced protection for high-risk installations (see illustration).

  • Compliance: Meets ASTM B230, B231, B232, B398, B399, B400, and ICEA specifications.

Construction Details

Conductor

  • Material:

    • AAC: 1350-H19 aluminum (compressed or full compact stranding).

    • AAAC: Aluminum alloy for increased strength.

    • ACSR: Aluminum-clad steel reinforced for high mechanical load applications.

  • Stranding: Concentrically stranded for flexibility and reduced electrical losses.

Covering

  • Material:

    • HDPE: High-density polyethylene for lightweight, track-resistant performance.

    • XLPE: Crosslinked polyethylene for superior thermal and chemical resistance.

  • Function: Prevents instantaneous flashovers during tree or object contact.

Optional Shield

  • Strand Shield: Additional conductive layer for electrostatic protection in high-interference zones.
