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.
