OVERHEAD SERVICE DROP CABLE

Overhead Service Drop Cable is an aerial electrical cable assembly designed to deliver secondary electricity from a utility pole's distribution lines to a residential or commercial building's service entrance. Operating at 600 volts or less, these self-supporting cables are engineered with heavy-duty weatherproofing to withstand extreme temperatures, UV radiation, wind, rain, and heavy ice loading.

The primary difference lies in the number of insulated phase conductors twisted around the bare neutral messenger wire, which determines their voltage and phase capabilities:

• Duplex Service Drop: Features one insulated phase conductor. Best for single-phase 120V applications, temporary construction site power, or outdoor street lighting.
• Triplex Service Drop: Features two insulated phase conductors. This is the industry standard for traditional residential 120/240V split-phase services.
• Quadruplex Service Drop: Features three insulated phase conductors. Engineered specifically for commercial, industrial, or agricultural applications requiring three-phase power (such as 120/208V or 277/480V systems).

Yes. We specialize in custom-cut-to-length orders with no extra charges. You don’t need to purchase a full master reel—simply specify the exact footage your project requires, and our team will cut, reel, and prepare your order for immediate dispatch.

We process orders rapidly and offer fast, reliable shipping across the country. Standard orders are typically delivered between 2-4 business days. Expeditd shipping is available on the checkout page. Whether you need a short run of Triplex for a residential hookup or bulk Quadruplex for a commercial development, we get your material delivered exactly when and where you need it.

Aluminum is the global utility standard for overhead power distribution because of its physical and economic advantages:

• Weight Reduction: Aluminum is significantly lighter than copper. This drastically reduces mechanical tension over long aerial spans, requiring less structural support at the pole and building weatherhead.
• Cost Efficiency: Aluminum is vastly more economical than copper, helping contractors and utility providers keep large-scale project costs down.
• Weight-to-Conductivity Ratio: While copper is more conductive by physical volume, one pound of aluminum carries the equivalent electrical current of two pounds of copper.

Service drop cables are built to endure harsh atmospheric conditions using highly specialized components:

• Conductors: Concentric stranded 1350-H19 aluminum or rugged AA-8000 series aluminum alloy.
• Insulation: Black, sunlight-resistant Cross-Linked Polyethylene (XLPE), which offers a superior 90° temperature rating compared to standard Polyethylene (PE) rated at 75°.
• Neutral Messenger Wire: Provides both the electrical neutral path and the mechanical tensile strength to support the cable's span. Messenger wires are available in All Aluminum Conductor (AAC), All Aluminum Alloy Conductor (AAAC), or steel-reinforced Aluminum Conductor Steel Reinforced (ACSR).

No. Using regular building wire for an overhead span is highly dangerous, violates the National Electrical Code (NEC), and poses immediate fire and electrocution risks. Standard building wires lack the heavy-duty, UV-stabilized weatherproofing required to survive outdoor exposure, and they do not possess the mechanical tensile strength to support their own weight across a span without stretching or snapping.
