OVERHEAD SERVICE DROP CABLE

Overhead Service Drop Cable, commonly known as a service drop, is a set of aluminum electrical wires that run through the air from a utility pole to a home or business. This suspended cable is the standard way buildings get their electricity from the main power grid. They are typically classified by the number of conductors they contain (duplex, triplex, or quadruplex) depending on whether the service is single-phase or three-phase.

Aluminum Overhead Service Drop Cable

Aluminum Overhead Service Drop cable is the industry standard for delivering secondary electrical power from utility poles to residential or commercial service entrance headers. Designed specifically for aerial installations, this cable features high-strength 1350-H19 aluminum phase conductors insulated with weather-resistant Cross-Linked Polyethylene (XLPE) or High-Density Polyethylene (HDPE). The assembly is supported by a central neutral messenger made of ACSR (Aluminum Conductor Steel Reinforced), AAC, or 6201 alloy, which provides the necessary tensile strength to withstand wind, ice loading, and long spans. Whether configured as Duplex, Triplex, or Quadruplex, these cables are engineered for 600V applications and offer a lightweight, cost-effective alternative to copper for reliable overhead power distribution.

Key Features
  • Weather-Resistant Insulation: Phase conductors are protected by black XLPE or HDPE jackets designed to resist UV degradation, moisture, and extreme temperature swings.
  • High-Strength Neutral Messenger: Features a dedicated supporting messenger (often ACSR) to handle mechanical tension and prevent cable sagging over long distances.
  • Lightweight Aluminum Design: Utilizes 1350-H19 series aluminum for an optimal strength-to-weight ratio, reducing strain on utility poles and mounting hardware.
  • Versatile Configurations: Available in Duplex (one hot), Triplex (two hots), and Quadruplex (three hots) to support single-phase or three-phase electrical services.
  • Industry Standards: Manufactured to meet or exceed ASTM B-230, B-231, B-232, and B-399 specifications, as well as ANSI/ICEA S-76-474 requirements.
Common Applications
  • Residential Service Drops: The primary cable used to run power from a utility transformer to a home's weatherhead.
  • Temporary Construction Power: Frequently used to provide overhead power to temporary poles on building sites.
  • Pole-to-Pole Distribution: Ideal for secondary distribution between utility poles in rural or residential areas.
  • Outdoor Area Lighting: Used to provide overhead power to streetlights, parking lot poles, and security lighting systems.
  • Farm & Agricultural Wiring: Deployed for overhead power runs between barns, silos, and other remote outbuildings.
  • Industrial Complex Power: Used for overhead secondary feeders in large manufacturing or warehousing facilities.
  • Municipal Utility Projects: Standard for city-wide infrastructure upgrades and overhead electrical grid maintenance.
