Duples Drop Wire 6/7 Duplex 1*6AWG+6AWG Aluminum Service Cable Abstract​ 1. Product Overview​ The Duples Drop Wire 6/7 Duplex 16AWG+6AWG Aluminum Service Cable is a specialized overhead service cable designed for connecting utility distribution lines to residential, commercial, and small industrial buildings. The "6/7" designation refers to the stranding configuration (6 or 7 strands), while "16AWG+6AWG" indicates two 6 American Wire Gauge (AWG) aluminum conductors. This duplex structure combines two insulated conductors in a single cable, streamlining installation and ensuring reliable power delivery from the main grid to end-users.​ 2. Structural Composition​ 2.1 Conductors​ The cable features two 6AWG aluminum conductors, each composed of high-purity aluminum (1350 series) with a conductivity of 61% IACS. The conductors are stranded with either 6 or 7 strands (0.8-1.0mm diameter each) to enhance flexibility, facilitating easy bending during installation. The stranded design also improves tensile strength, allowing the cable to withstand the mechanical stresses of overhead deployment.​ 2.2 Insulation and Sheathing​ Each conductor is insulated with high-density polyethylene (HDPE) or cross-linked polyethylene (XLPE), providing a thickness of 0.8-1.2mm. This insulation offers excellent dielectric properties, UV resistance, and moisture protection. The duplex configuration bonds the two insulated conductors together with a thin web, creating a unified structure that reduces wind resistance and simplifies handling while maintaining electrical isolation between conductors.​ 3. Performance Characteristics​ 3.1 Electrical Performance​ Current-Carrying Capacity: Each 6AWG conductor supports a continuous current of 55-65A (30°C ambient temperature), suitable for typical residential and small commercial loads.​ Voltage Rating: Designed for low-voltage applications (600V maximum), compatible with standard 120/240V service connections.​ Low Resistance: DC resistance of 0.408Ω/km per conductor at 20°C, ensuring minimal power loss during transmission.​ 3.2 Mechanical and Environmental Performance​ Tensile Strength: Minimum breaking load of 1.8kN, enabling safe installation across spans up to 50 meters between utility poles and building entry points.​ Flexibility: Minimum bending radius of 10 times the cable diameter (≈25mm), allowing easy routing around obstacles.​ Weather Resistance: UV-stabilized insulation withstands -40°C to +70°C temperatures, while moisture resistance prevents water ingress in humid environments.​ Durability: Resistant to abrasion, corrosion, and chemical exposure, ensuring a service life of 25+ years under normal operating conditions.​ 4. Application Scenarios​ Residential Service Connections: Linking utility lines to homes, providing power for household appliances and lighting.​ Small Commercial Buildings: Supplying electricity to shops, offices, and small businesses with moderate power demands.​ Rural Electrification: Ideal for connecting remote homes and farms to distribution networks, withstanding harsh outdoor conditions.​ Temporary Installations: Serving as temporary power links for construction sites or events, thanks to its easy installation and removal.​ 5. Conclusion​ The Duples Drop Wire 6/7 Duplex 1*6AWG+6AWG Aluminum Service Cable offers a reliable, cost-effective solution for low-voltage overhead service connections. Its duplex design, high-quality aluminum conductors, and robust insulation ensure efficient power delivery, easy installation, and long-term durability in diverse residential and light commercial applications.
