Triplex 600 Volt RHH/RHW-2 or USE-2 AlumaFlex® Underground Service Entrance

Download PDF Download Excel Table

Construction:

Conductor:Conductors are stranded, compressed Triple E per ASTM 800 and 801
Insulation:Cross Linked Polyethylene (XLPE) Type RHH/RHW-2 or USE-2
Neutral:Cross Linked Polyethylene (XLPE) with three Yellow Extruded Stripes (YES)

Applications and Features:

Conductors are stranded, compressed aluminum Triple E AA8000 (8176-H24), insulated with cross-linked polyethylene Type RHH/RHW-2 or USE-2. Neutrals are identified by three yellow extruded stripes. Cables with “YES” neutrals have sequential footage markers. Conductors are durably surface printed for identification. Two-phase conductors and one neutral conductor are cabled together to produce the triplex cable configuration. These cables are capable of operating continuously at the conductor temperature not in excess of 90°C for normal operation in wet and dry locations, 130°C for emergency overload, and 250°C for short circuit conditions.

Notes:
1. Inductive reactance assumes cables are cradled in conduit, and the neutral is carrying no current.
2. Conductors assumed to be reverse lay stranded, compressed construction.
3. Phase spacing assumes cables are touching.
4. Resistances shown are for the phase conductors only.
5. Ampacities based upon 2023 NEC Table 310.16 Ampacities of Insulated Conductors with Not More Than Three Current-Carrying Conductors in Raceway, Cable, or Earth (Directly Buried)
