MV Copper Conductor XLPE Insulation SEU Concentric Neutral Cable
1. Application:
These requirements 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. 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 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.
3. Characteristic:
Single core type round wit:h full neutral entrance cable
Single core type round with less neutral entrance cable
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
Three core type round with less neutral entrance cable
4. Standard:
IECAS-94-649 CSA C68.3
