Low Voltage Duplex Service Drop Cable For Power Transmission

Low Voltage Duplex Service Drop Cable For Power Transmission

Duplex service drop cable is a type of electrical cable commonly used to deliver power from utility poles to residential buildings, particularly for overhead service connections. It consists of two conductors: one insulated phase conductor and one bare neutral conductor. Here are the key aspects of duplex service drop cables:

Components and Structure

1. Phase Conductor:

   • Material: Typically aluminum, which is lightweight and cost-effective.
   • Insulation: Covered with cross-linked polyethylene (XLPE) or polyethylene (PE) insulation for protection against weather and mechanical damage.

2. Neutral Conductor:

   • Material: Often aluminum, sometimes reinforced with a steel core to provide additional strength and support.
   • Bare: The neutral conductor is typically uninsulated and serves both as the electrical neutral and as the mechanical support for the assembly.

3. Configuration:

   • The phase conductor and the neutral conductor are twisted together, forming a duplex configuration that is compact and easy to handle.

Advantages

1. Cost-Effective: Aluminum conductors are less expensive and lighter than copper, making duplex service drop cables economical for utility companies.
2. Lightweight: Easier to install and requires less robust supporting structures compared to heavier copper cables.
3. Durability: Insulated phase conductor provides protection against environmental factors such as UV radiation, moisture, and abrasion.
4. Simplicity: The duplex design simplifies installation and maintenance.

Applications

• Residential Service Drops: Primarily used to provide electrical service from the utility pole to individual residential buildings.
• Short-Distance Power Distribution: Suitable for short-distance overhead power distribution in both urban and rural settings.

Specifications

• Voltage Ratings: Generally used for low voltage applications, typically around 600 volts.
• Sizes: Available in various sizes to match different electrical load requirements. Sizes are usually specified by the cross-sectional area of the conductors (e.g., 6 AWG, 4 AWG).
