Aluminum Conductor Quadruplex Overhead Service Drop Cable
Service Drop Cable is a four-conductor aerial cable designed for delivering three-phase power from a utility pole to the service entrance of commercial or residential buildings. It consists of three insulated aluminum conductors (phase conductors) and one bare aluminum conductor (neutral messenger) twisted together in a quadruplex configuration.
This cable is self-supporting, highly durable, and suitable for overhead installations where reliability, weather resistance, and ease of handling are critical.

Typical Construction
| Component | Description |
|---|---|
| Phase Conductors | Three black-insulated aluminum conductors |
| Neutral Messenger | Bare aluminum wire, supports cable weight and serves as neutral |
| Assembly | Twisted quadruplex construction, pre-assembled for aerial span use |
Available Sizes (Common Configurations)
| Size (AWG/kcmil) | Phase Conductors | Neutral Messenger | Ampacity (Approx.) |
|---|---|---|---|
| 6-6-6-6 | 6 AWG Insulated | 6 AWG Bare | ~55 Amps |
| 4-4-4-2 | 4 AWG Insulated | 2 AWG Bare | ~85 Amps |
| 2-2-2-4/0 | 2 AWG Insulated | 4/0 AWG Bare | ~115 Amps |
| 1/0-1/0-1/0-2/0 | 1/0 AWG Insulated | 2/0 AWG Bare | ~150 Amps |
