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.
Key Features
Voltage Rating: 600 Volts (phase-to-phase)
Conductor Material: 1350-H19 aluminum or optional 6201-T81 aluminum alloy
Stranding: Class A concentric stranded aluminum
Configuration: Three insulated phase conductors + one bare neutral messenger
Insulation: XLPE (Cross-Linked Polyethylene) or HDPE (High-Density Polyethylene), black, UV-resistant
Temperature Rating:
90°C with XLPE insulation
75°C with HDPE insulation
Meets or exceeds: ASTM B-230, B-231, B-232, and ICEA S-76-474
Applications
Quadruplex Service Drop Cables are typically used for:
Three-phase residential or commercial overhead service
Overhead power distribution from pole to building
Rural electrification projects
Permanent or temporary power installations
Not intended for underground use. Always follow local utility and code requirements.
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 |
| 4/0-4/0-4/0-4/0 | 4/0 AWG Insulated | 4/0 AWG Bare | ~230 Amps |
Ampacity is approximate and may vary depending on ambient conditions and installation method.
