11kv (15) Kv 90c Sac Spaced Aerial Cable 300mcm Three Layer Tree Wire​ The 11kv (15kv) 90c Sac Spaced Aerial Cable 300mcm Three Layer Tree Wire is a high-performance solution for medium-voltage overhead distribution, engineered to excel in demanding environments. Rated for 11kv and 15kv systems with a 90°C temperature tolerance, it features a 300mcm (thousand circular mils) conductor and a specialized three-layer insulation design, making it ideal for tree-rich or forested areas.​ The "Sac" (Spaced Aerial Cable) design incorporates durable spacers to maintain conductor separation, reducing short-circuit risks and enhancing stability across spans up to 80 meters. Its three-layer insulation—typically XLPE/polyethylene/weather-resistant coating—delivers superior protection against UV rays, moisture, and tree-related abrasion, critical for minimizing outages in wooded regions.​ With a 300mcm high-conductivity aluminum core, it handles continuous currents up to 350A, supporting rural electrification, suburban grids, and renewable energy connections. Compliant with IEEE and IEC standards, this tree wire balances thermal resilience (90°C operation) and mechanical strength, offering a low-maintenance, long-lifespan (25+ years) solution for medium-voltage
