SPEC 83033

Triplex 600 Volt Underground Service Entrance. Hi-Score Optional

Aluminum Conductor. Cross-linked Polyethylene (XLP) Insulation. HI-SCORE available upon request.

...

Construction:

  1. Conductor:Conductors are stranded, compressed 1350-H16/H26 (3/4 Hard) aluminum
  2. Insulation:Cross Linked Polyethylene (XLPE). LLDPE or HDPE based polymer
  3. Neutral:Cross Linked Polyethylene (XLPE) with three Yellow Extruded Stripes (YES)

Applications and Features:

Conductors are stranded, compressed 1350-H16/H26 (3/4 Hard) aluminum, insulated with cross-linked polyethylene. 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. Triple parallel inductive reactance calculation assumes the phase conductors are adjacent to one another.
    3. Conductors assumed to be reverse lay stranded, compressed construction.
    4. Phase spacing assumes cables are touching.
    5. Resistances shown are for the Phase conductors only.
    6. Ampacity based on 90°C conductor temperature, 20°C ambient, RHO 90, 100% load factor.
