Applications
Covered Line ÌÇÐÄVlog´«Ã½ is used primarily for overhead secondary distribution lines. It is not an electrically insulated conductor and is treated as bare conductor when installed.
Construction
Conductors are aluminum alloy 1350-H19, 6201-181, or ACSR conductors, concentrically stranded and covered for weather proofing with polyethylene, high density polyethylene (HD) or crosslinked polyethylene (XLP).
