“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.“

Key Features & Benefits: 6-6 Duplex Overhead Service Drop Cable

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 90C 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.
