Concentric Cable Copper Conductor

1. APPLICATIONS

These requirements cover Type USE and USE-2 (below-ground) and Type SE (above-ground) power cables for installation
in accordance with Article 338 and other applicable parts of the National Electrical Code (NEC). These cables are for the
service-entrance and other (NEC) uses described in 1.4 – 1.8. In a multiple-conductor cable that is other than submersible-pump
cable and does not have a grounding conductor it is appropriate to have one circuit conductor without insulation. It is also
appropriate for a submersible pump cable to have a grounding conductor and for Type USE and USE-2 cables to have an
insulated grounding conductor. Each insulated conductor in these cables is rated for 600 V. Type USE cable has thermoset
insulation, except for the HDPE portion of HDPE-over-XLPE insulation where used for single-conductor Type USE cable. Type
SE cable has thermoset or thermoplastic insulation.

2. SPECIFICATIONS

Type SE cable meets or exceeds UL Standard 44 for XHHW-2 conductors or UL 83 for THW conductors, UL Standard 854.

3. CONSTRUCTION

Type SE cable is constructed with sunlight resistant Type XHHW-2 conductors or Type THW conductors. Copper conductors
are annealed (soft) copper. Cable assembly plus reinforcement tape are jacketed with sunlight resistant thermoset or
thermoplastic material, Available as 1 conductor with a concentric ground, 2 conductor with a round and flat or concentric round,
or 3 conductor with a bare ground. SE cable is jacketed with gray sunlight resistant thermoset or thermoplastic material.
