SPEC 83227

Triplex XLPE Service Drop. AAC Neutral - Messenger

Aluminum Conductors With Crosslinked Polyethylene Insulation.

...

Construction:

  1. Conductor:Conductors are stranded, compressed 1350-H19 aluminum
  2. Insulation:Cross Linked Polyethylene (XLPE)
  3. Messenger:AAC Neutral

Applications and Features:

Used to supply power, usually from a pole-mounted transformer, to the user's service head where connection to the service entrance cable is made. To be used at voltages of 600 volts phase-to-phase or less and at conductor temperatures 90°C for crosslinked polyethylene (XLP) insulated conductors.

Specifications:

  • ASTM B230 Aluminum, 1350-H19 Wire for Electrical Purposes
  • ASTM B231 Standard Specification for Concentric-Lay-Stranded Aluminum 1350 Conductors
  • ASTM B901 Standard Specification for Compressed Round Stranded Aluminum Conductors Using Single Input Wire Construction. (The number of strands for both phase and neutral may differ)
  • ICEA S-76-474 Standard for Neutral-Supported Power Cable Assemblies with Weather-Resistant Extruded Insulation Rated 600V

    Notes:
    1. DC resistances include a 1% length factor for plexing.
    2. Inductive reactance assumes the neutral is carrying current.
    3. Phase conductors assumed to be reverse lay stranded, compressed construction.
    4. Phase spacing assumes cables are touching.
    5. Resistances shown are for the phase conductor only.
    6. Sizes of AAAC neutrals are not the AAAC size, but are the size of an ACSR of equal diameter.
    7. Ampacity based on conductor temperature of 90°; ambient temperature of 40°C; emissivity 0.9; 2 ft./sec. wind in sun.
