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-phase or 480 volts phase-to-ground, to a normal temperature rating of the service conductor temperature of 90 °C.
