Covered Line Wire Aluminum Conductor
Used primarily for overhead secondary distribution lines. Not an electrically insulated conductor and is treated as bare conductor when installed.
Applications
Where it is used
- Overhead secondary distribution lines
Construction
What it's built from
- Conductor
- Aluminum alloy 1350-H19, 6201-T81, or ACSR conductors, concentrically stranded.
- Covering
- Polyethylene, high density polyethylene (HDPE), or cross-linked polyethylene (XLP).

All values are nominal and subject to correction. Code words apply to conventional high density polyethylene covered ACSR and AAC line wires. Line wire with AAAC 6201-T81 conductor available upon request. Ampacity ratings are based on 75°C conductor temperature, 25°C ambient temperature at sea level, emissivity 0.91, and coefficient of absorption 0.95.
