Covered Line Wire is used primarily for overhead secondary distribution lines. It is not an electrically insulated conductor and is treated as bare conductor when installed.
Conductors are aluminum alloy 1350-H19, 6210-T81, or ACSR conductors, concentrically stranded and covered for weather proofing with polyethylene, high density polyethylene(HD)or crosslinked polyethylene(XLP).

Available in 500 ft coils or long lengths on reels. The data is approximate and subject to normal manufacturing tolerances.
For 6201 aluminum conductors diameter equivalent to ACSR construction or 1350 aluminum equivalent. Ampacity ratings based on 75oC conductor temperature 25 oC ambient temperature elevation-sea level. Emissivity 0.91, coefficient of absorption 0.95. Thermal reisitivity of covering-375 oC-Cm2/Watt-CM. Wind speed 2ft/sec in sun.
To determine current ampacity by conductor size, please consult The National Electric Code, latest edition.
