Nexans Underground Secondary Distribution Cables may be used for underground secondary distribution applications at 600 volts or less. They may be either directly buried or installed in ducts, in either wet or dry locations. These cables are designed to operate at a conductor temperature not exceeding 90°C for normal operation, 130°C for emergency overloads, and 250°C under short circuit conditions.
As a result of their enhanced mechanical properties, Nexans Ruggedized Underground Secondary Distribution Cables are especially suited for applications requiring superior resistance to abrasion, scoring and crushing.
Conductor Construction
Solid or Class B compressed concentric-lay-stranded 1350 aluminum.
Phase Conductor Insulation Material*
The insulation on the phase conductor(s) is black low-density crosslinked polyethylene.
Neutral Conductor Insulation Material*
The insulation on the neutral conductor may be either:
- Black low-density crosslinked polyethylene
- Black low-density crosslinked polyethylene with three extruded yellow stripes
*Note: The ruggedized construction uses an inner layer of low-density crosslinked polyethylene, with an outer layer of high-density crosslinked polyethylene.
Assembly
Multiplex constructions are twisted together with a left hand lay not greater than 60 times the outside diameter of a single phase conductor.
Markings
The insulation will bear the following surface markings:
- Nexans
- Year and Plant of Manufacture
- Phase Conductor Size
- 600V
- Phase identification on quadruplex cables only
Standard
Manufactured and tested to ANSI/ICEA S-105-692-2004 (Standard for 600 Volt Single Layer Thermoset Insulated Utility Underground Distribution Cables) or ANSI/ICEA S-81-570-2005 (Standard for 600 Volt Rated Cables of Ruggedized Design for Direct Burial Installations as Single Conductors or Assemblies of Single Conductors).
UL listing and marking for Type USE-2 is available upon request.
