"The industry standard for 120/240V single-phase overhead utility drops, residential main power feeds, and temporary jobsite distribution. Engineered for dependable 600V aerial power delivery from utility lines to building weatherheads, this 3-conductor triplex cable features two insulated aluminum phase conductors, weather-resistant XLP insulation, and a heavy-duty bare steel-reinforced ACSR neutral messenger built to withstand environmental strain."
Key Features & Benefits: 4-4-4 Triplex Overhead Service Drop Cable
The 4-4-4 Periwinkle Triplex Cable is the go-to choice for overhead single-phase 120/240V secondary power distribution requiring higher current capacity than standard #6 wire. Designed to span overhead gaps from utility pole transformers to residential weatherheads and service masts, it provides a balanced, sag-resistant solution for main service drops and temporary construction power feeds.
By pairing two 7-strand 1350-H19 series aluminum phase conductors with a high-tensile ACSR neutral messenger, Periwinkle triplex provides lightweight, low-maintenance power delivery with exceptional physical strength. The cross-linked polyethylene (XLP) insulation offers superior protection against sunlight, freezing rain, and severe atmospheric wear.
600V Aerial Reliability: Rated for continuous 120/240V aerial service (up to 600V max phase-to-phase) at conductor temperatures up to 90°C with XLP insulation.
High-Tensile ACSR Messenger: Features a 6/1 steel-reinforced ACSR neutral messenger delivering 1,860 lbs of breaking strength to prevent sag and withstand heavy ice and 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.
