Applications:

Duplex Overhead Secondary Distribution Cable assemblies consist of one insulated phase conductor and a bare neutral conductor.  They are intended for use either as a service drop cable between a power pole and the service entrance, or as a secondary distribution cable between poles.   Their use should be limited to circuits not exceeding 600 volts phase-to-phase and a 90°C normal conductor temperature.

Construction:

Neutral Conductor Construction: Cable assemblies are available with the following neutral conductors:

• Aluminum conductors, coated-steel reinforced (ACSR), concentric-lay-stranded
• Aluminum alloy 1350-H19 hard-drawn, concentric-lay-stranded
• Aluminum alloy 6201-T81, concentric-lay-stranded

Insulation Material:
The standard insulation on the phase conductor is black low-density crosslinked polyethylene (XLPE)

Alternatively, black linear low-density polyethylene (LLDPE) insulation with a 75°C temperature rating is available upon request.

The XLPE insulation meets the requirements of ANSI/ICEA S-76-474-2004 (Standard for Neutral-Supported Power Cable Assemblies with Weather-Resistant Extruded Insulation Rated 600 Volts).

The LLDPE insulation meets the requirements of  ASTM Standard D1248-05 (Standard Specification for Polyethylene Plastics Molding and Extrusion Materials).

Assembly
The insulated phase conductor is twisted around the bare neutral conductor with a right-hand lay length of 25 to 60 times the diameter of the phase conductor.

Standards:

Overhead Secondary Distribution Cable is manufactured and tested in accordance with ANSI/ICEA S-76-474-2004 (Standard for Neutral-Supported Power Cable Assemblies with Weather-Resistant Extruded Insulation Rated 600 Volts).
