Applications
Covered line wire is used primarily for 600v secondary overhead power distribution lines. It is not an electrically insulated conductor and often considered a bare conductor.

Construction
The aluminum conductors are 1350-H19 aluminum, 6201-T81 Aluminum Alloy, or ACSR conductors, concentrically stranded and covered for weather proofing with polyethylene, high density polyethylene (HDPE) or cross-linked polyethylene(XLPE).

Standards
ASTM B-230 – Aluminum 1350-H19 Wire for Electrical Purposes
