Aerial Bundle Cables (ABC)

Service drop cables are composed of one or more concentric-lay-stranded Aluminum 1350 phase conductors insulated with an extruded layer of cross-linked polyethylene compound and assembled with one neutral conductor of All Aluminum Conductors (AAC); Aluminum-Alloy Conductors 6201-T81 (AAAC); Aluminum Conductors, Steel-Reinforced (ACSR); or Aluminum Conductors, Aluminum-Clad Steel Reinforced (ACSR/AW).

The neutral conductor may be bare or covered with an extruded layer of cross-linked polyethylene compound.

Applications:

  • The use of these service drop or secondary distribution cables is limited to circuits, not exceeding 600 volts phase-to-phaseor 480 volts phase-to-ground, to a normal temperature rating of the service conductor temperature of 90 °C.

Standards:

  • IEC 60502, IEC 60228, IEC 61089, BS EN 50182
  • ASTM B549, ASTM B232
  • ANSI / ICEA S-76-474
