Nexans Underground Secondary Distribution Cables may be used for underground secondary distribution and service entrance 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.
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
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
- USE-2
- Phase identification on quadruplex cables only
Standard
Manufactured and tested to UL 854 (Service Entrance Cables) as Type USE-2. Also meets ANSI/ICEA S-105-692-2004 (Standard for 600 Volt Single Layer Thermoset Insulated Utility Underground Distribution Cables).
