Covered Line Wire

to, overhead secondary distribution lines. Installed on insulators, otherwise treated as a bare conductor.

Ease of erection and stringing

Practically no tree-trimming required

Less maintenance

Relative immunity to short circuits caused by external forces (wind, fallen branches), unless they abrade the insulation.

Aluminum alloy 1350-H19, 6201, or ACSR conductors, concentrically stranded, covered with polyethylene or crosslinked polyethylene (XLPE). The covering provides circuit protection against momentary contact with other conductors or trees. Because the covering carries no voltage rating, the conductors must be installed on insulators adequate for the intended service voltage. The user should consider the dielectric compatibility of the covering, insulator and conductor/insulator tie.

1.Conductors are available in the following constructions

Aluminum conductor, steel reinforced (ACSR), concentric-lay stranded

Aluminum alloy 1350-H19 hard-drawn, concentric-lay stranded

Medium hard-drawn copper, solid or concentric-lay-stranded

2.Covering Material

The standard covering on the conductor is black linear low-density polyethylene (LLDPE). Alternatively, a covering of black low-density crosslinked polyethylene (XLPE) with a 90°C temperature rating is available upon request.
