Covered Line Wire-Aluminum Conductor

1.       Applications

Covered Line Wire-Aluminum Conductor is used primarily for overhead secondary distribution lines.It is not an electrically insulated conductor and is treated as bare conductor when installed.

2.       Construction

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).

3.       Standards

ASTM B-230,B-231,B-232 and B-399

ICEA S-61-402 and S-66-524
