Nexans Multiplexed Overhead Secondary Distribution Cable assemblies consist of one or more insulated conductors 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.
Phase Conductor Construction
The phase conductors are aluminum alloy 1350-H19 hard-drawn, compressed concentric-lay-stranded.
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(s) 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
One or more insulated phase conductors are twisted around the bare neutral conductor with a right-hand lay length of 25 to 60 times the diameter of one phase conductor.
Markings
The covering will bear the following surface markings:
- Nexans
- Year and Plant of Manufacture
- Phase Conductor Size
- XLPE or LLDPE
- 600V
- Phase identification on quadruplex cables only
Standard
Nexans 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).
