"The industry standard for 120V overhead utility drops, outdoor lighting, and temporary jobsite power. Engineered for dependable 600V aerial power delivery, this 2-conductor duplex cable features weather-resistant XLP insulation and a heavy-duty steel-reinforced ACSR neutral messenger built to withstand environmental strain."
The 6-6 Shepherd Duplex Cable is the go-to choice for overhead single-phase 120V secondary distribution. Built to bridge the gap between utility poles and weatherheads, it provides a stable, sag-resistant solution for overhead power drops, construction site temp power, and street lighting installations.
By utilizing 1350-H19 series aluminum conductors paired with a high-tensile ACSR neutral messenger, Shepherd duplex provides maximum physical strength with lightweight ease of installation. The cross-linked polyethylene (XLP) insulation offers extreme protection against sunlight, freezing temperatures, and environmental wear.
600V Aerial Reliability: Rated for continuous 120V aerial service (up to 600V max) at conductor temperatures up to 90°C with XLP insulation.
High-Tensile ACSR Messenger: Features a 6/1 steel-reinforced ACSR neutral messenger delivering 1,190 lbs of breaking strength to prevent sag and withstand ice/wind loads.
Sunlight & Weather-Resistant XLP: Heavy-duty black cross-linked polyethylene insulation prevents UV degradation, cracking, and moisture damage in outdoor environments.
Cut to Length by the Foot: Order only the exact span length needed for your project, eliminating jobsite waste and unused spools.
Application: Overhead secondary power drops (120V single-phase), temporary jobsite power feeds, and outdoor/street lighting runs.

Shepherd 6-6 Duplex cable is designed for 120V single-phase aerial power supply. It is primarily used to run overhead service drops from utility poles to building weatherheads, power outdoor or street lighting runs, and provide temporary overhead power feeds for construction sites.
No. Duplex cable contains only two conductors (1 insulated phase wire + 1 bare neutral messenger), which powers single 120V circuits. If you need a 120/240V service drop for a main house electrical panel, you will need a 3-conductor Triplex cable (such as 6-6-6 Voluta) that includes two insulated phase wires and a bare neutral.
The bare messenger wire acts as both the neutral conductor and the structural support wire that holds the cable in the air. Shepherd uses an ACSR (Aluminum Conductor Steel Reinforced) messenger, which features a steel core strand surrounded by aluminum. This steel core provides superior high-tensile breaking strength (1,190 lbs) to prevent line sag over longer span distances and withstand heavy wind or ice accumulation.
No. Duplex service drop wire is engineered strictly for overhead aerial applications. Its XLP insulation is weather- and sunlight-resistant for outdoor exposure, but it is not rated for direct burial or underground conduit installation. For underground service runs, use URD (Underground Residential Distribution) cable or USE-2 wire.
#6 AWG Duplex with XLPE (Cross-Linked Polyethylene) insulation is generally rated for up to 85 Amps in free-air overhead installations at 90°C conductor temperature. Always consult NEC Table 310.17 / local code requirements and equipment terminal ratings to ensure proper sizing for your specific voltage drop and load.
Yes! At Wire America, all overhead service drop cables are custom cut to your exact required length—eliminating extra spools and wasted footage. Simply enter your required footage to order, and we’ll cut, process, and ship your order directly to your shop or job site from our regional distribution centers located throughout the US. Standard orders typically arrive within 2–4 business days, with expedited shipping options available at checkout.
