Secondary Distribution Duplex Unjacketed Overhead Neutral Supported Ns75/Ns90 Service Drop Cables​ These duplex unjacketed overhead service drop cables—Ns75 and Ns90 variants—are engineered for secondary distribution (600V max), featuring a neutral-supported design for residential and light commercial power delivery. The unjacketed construction reduces weight while maintaining durability in overhead applications.​ Ns75 handles 75A, ideal for small homes with basic appliances, while Ns90 delivers 90A to support high-demand loads like EV chargers and heat pumps. The neutral conductor acts as both structural support (8kN tensile strength) and current return, enabling 50-meter spans between poles.​ Aluminum conductors (61% IACS) ensure efficient power transfer, with UV-resistant insulation on phase conductors. The duplex design simplifies installation, cutting labor time by 25%. Certified to ICEA S-76-474 and ASTM B230, they meet overhead service safety standards.​ Key SEO terms: Ns75 Ns90 duplex service drop, neutral supported overhead cable, unjacketed secondary distribution cable, 600V overhead service wire.
