Weatherproof Covered Line Wire is a single-conductor aluminum overhead cable designed for low-voltage power distribution. It features a non-insulated but weather-resistant covering, primarily used for aerial service drops from the utility pole to residential or commercial buildings.
Unlike fully insulated cables, this type offers mechanical protection and UV/weather resistance, while still behaving electrically like a bare conductor. It is widely used in utility distribution networks where insulation is not required but some environmental protection is desired.
Weatherproof Covered Line Wire
Key Features
Rated Voltage: 600V phase-to-phase
Conductor: Hard-drawn aluminum (AAAC or AAC)
Covering: Black weather-resistant thermoplastic (e.g., polyethylene)
Temperature Rating: Up to 75°C (HDPE) continuous operation
Installation: Aerial (overhead), pole-to-building service drop
Design: Single conductor, concentric stranded
Applications
Overhead service drop for residential or commercial buildings
Utility power distribution in urban and rural areas
Temporary or permanent aerial electrical connections
Use in areas with exposure to sunlight, moisture, and abrasion
⚠ Note: This is not an insulated conductor. It must be treated as live and installed with proper clearances and equipment in accordance with electrical codes.
Construction Details
| Component | Description |
|---|---|
| Conductor | Stranded aluminum (1350-H19 or AAAC) |
| Covering | Black weather-resistant polyethylene (not rated as insulation) |
| Stranding | Class A concentric-lay or compressed stranding |
| Marking | Surface-printed or indented for traceability |
Common Sizes & Ampacities
| Conductor Size (AWG/kcmil) | Stranding | Approx. OD (mm) | Ampacity (Air)** |
|---|---|---|---|
| 6 AWG | 7 strands | ~7.5 mm | ~55 Amps |
| 4 AWG | 7 strands | ~8.6 mm | ~70 Amps |
| 2 AWG | 7 or 19 strands | ~10.3 mm | ~95 Amps |
| 1/0 AWG | 19 strands | ~12.3 mm | ~125 Amps |
| 4/0 AWG | 19 strands | ~16.2 mm | ~230 Amps |
Ampacity is approximate and depends on environmental conditions and installation configuration.
