Overhead Service Drop Cable
Overhead Service Drop Cable supplied by ZMS – premium Duplex, Triplex, and Quadruplex Service Drop Cables.
Durable. Cost-Effective. Built for Overhead Utility Connections.
Perfect for overhead power distribution to residential, commercial, and rural areas.
Overhead Service Drop Cable Types
Overhead service drop cables are widely used to deliver electricity from utility poles to end-user premises. Depending on the customer service requirements (single-phase or three-phase), these cables are mainly classified into three types: two-core, three-core, and four-core. ZMS Manufacturing designs each cable type for specific applications, offering different conductor configurations and mechanical strengths to meet various installation needs.
Depending on the number of conductors and intended use, overhead service drop cables can be classified into three types: two-core, three-core, and four-core structures.
Duplex Service Drop Cable
Duplex service drop cable is used to carry single-phase power from the secondary power line to the service entrance or meter in a residence or small commercial building. It consists of two conductors: an insulated phase conductor and a bare aluminum neutral conductor.
Structure Description
- Conductor: 1350-H19 aluminum core, concentrically stranded
- Neutral: Bare AAC or ACSR conductor
- Insulation: Cross-linked polyethylene (XLPE) or polyethylene (PE)
- Assembly: Insulated conductors stranded over bare neutral core
Cable Characteristics
- Lightweight, easy to load, transport and install
- UV-resistant, wear-resistant, moisture-proof
- Excellent conductivity, high power transmission efficiency
- Suitable for short-distance transmission, economical and efficient
Technical Parameters
Size (AWG/kcmil) | Insulation Thickness (mm) | Approx. OD (mm) | Weight (kg/km) | Rated Voltage |
6 AWG | 1.14 | 13.2 | 106 | 600/1000V |
4 AWG | 1.14 | 14.5 | 152 | 600/1000V |
2 AWG | 1.14 | 16.8 | 231 | 600/1000V |
Triplex Service Drop Cable
The three-conductor service drop cable is used to deliver single-phase power from a pole-mounted transformer to the service entrance of a building. It contains two insulated phase conductors and a bare neutral conductor, which is generally used for mechanical support and grounding.
Triplex Overhead Wire Structure
- Conductor: 1350-H19 aluminum core concentric stranded wire
- Neutral: Aluminum stranded steel core (ACSR) or aluminum aluminate stranded wire (AAC)
- Construction: Three-strand stranded wire for increased flexibility
- Insulation: Cross-linked polyethylene (XLPE) or polyethylene (PE), color coded
Triplex Overhead Wire Characteristics
- Insulation jacket is UV and windproof, weatherproof, etc.
- Strong mechanical strength through AAAC or ACSR reinforced neutral wire
- Easy to install, lightweight, small sag
- Ideal for short-distance overhead power distribution in residential and rural areas
Triplex Wire Sizes & Technical Parameters
Conductor Size (AWG/kcmil) | Insulation Thickness (mm) | Approx. OD (mm) | Weight (kg/km) | Rated Voltage |
4 AWG | 1.14 | 17.5 | 225 | 600/1000V |
2 AWG | 1.14 | 20.3 | 287 | 600/1000V |
1/0 AWG | 1.52 | 23.6 | 412 | 600/1000V |
Quadruplex Service Drop Cable
The four-core service drop cable is designed for three-phase power supply to large residential, shopping malls or light industrial buildings. It consists of three insulated phase wires and one bare neutral wire.
Quadruplex Overhead Wire Structure
- Phase: 1350-H19 aluminum
- Neutral: AAC or ACSR, bare wire
- Insulation: XLPE or PE
- Construction: Four-core twisted cable, excellent mechanical properties
Quadruplex Cable Characteristics
- Efficient power transmission, three-phase power transmission
- Durable insulation, suitable for outdoor harsh environment use
- Reinforced neutral wire supports cable tension
- Low overhead line installation cost
Technical Parameters
Conductor Size (AWG/kcmil) | Insulation Thickness (mm) | Approx. OD (mm) | Weight (kg/km) | Rated Voltage |
2 AWG | 1.14 | 24.6 | 386 | 600/1000V |
1/0 AWG | 1.52 | 27.9 | 561 | 600/1000V |
4/0 AWG | 1.65 | 34.8 | 885 | 600/1000V |
Difference - Duplex & Triplex & Quadruplex
A clear understanding of the structures among Duplex, Triplex, and Quadruplex cables can not only help learners understand cables, but also enable purchasers to choose the required cables most correctly.
| Type | Number of Conductors | Typical Application | Power Supply Type | Key Features |
|---|---|---|---|---|
| Duplex | 2 (1 phase + 1 neutral) | Single-phase service to residential buildings | Single-phase | Simple structure, ideal for short runs |
| Triplex | 3 (2 phases + 1 neutral) | Single-phase power from transformer to home | Single-phase | Neutral also acts as messenger support wire |
| Quadruplex | 4 (3 phases + 1 neutral) | Three-phase power to commercial or large loads | Three-phase | Suitable for high load capacity applications |
