Copper concentric cable

Service Entrance Cable, Type SE, In flat and In round cable, 600V
Concentric conductor with 100% and non 100% coverage
Indicidual Conductor Rated XHHW-2 or THW
Jacket and Individual Conductor Sunlight Resistant

1. Appliction
These requiremnets cover Type USE and USE-2 (below-ground) and Type SE (above-ground) power cable 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 sunmersibe 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 600V. Type USE cable has thermose insulation, except for HDPE portion of HDPE-over-XLPE insulation where used for single-conductor Type USE cable. Type USE cable has thermoset or thermoplatic insulation.

2. Specification
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 conductor 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 concetric 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.

4. Type

Single core type round with full neutral and communication cores entrance cable
Two core type Flat with full neutral entrance cable
Two core type round with full neutral entrance cable
Three core type round with full neutral and communication cores entrance cable
