Three Core Aluminum Conductor XLPE Insulated Power Cable Medium Voltage 21/35kV
Shenghua 21/35kV Aluminum XLPE Cable: The Geologically-Immune Power Network
Shenghua redefines cable resilience with its triple-core aluminum-conductor XLPE cables, engineered to conquer seismic shifts, coastal erosion, and mining stress. Trusted in 60+ disaster-prone regions and compliant with IEC 60502-1, KEMA, and GB/T 12706, these cables merge 40% cost-efficiency vs. copper with 50-year lifespans in corrosive zones.
Ⅰ. Material Science: Engineered for Geological Warfare
-
Aluminum Conductor Superiority
- Cost-Saving Durability: Compact stranded aluminum (IEC 60228 Class 2) slashes installation costs by 40% vs. copper while achieving ultra-low resistance (0.0778Ω/km for 3×400mm²) – critical for long-distance mining grids
- Thermal Immunity: Nano-modified XLPE insulation withstands 90°C continuous load, 250°C/5s short-circuit spikes, and UV/ozone degradation, extending service life in deserts and tropics
-
Triple-Shielded Defense Architecture
- EMI Neutralization: Copper tape screen blocks electromagnetic interference from substations, ensuring signal integrity for IoT grid sensors
- Sheath Armor: FR-PVC (IEC 60502 ST2) with 3.1mm thickness resists rock abrasion, salt spray, and termite infiltration – proven in Indonesia’s monsoon tunnels
Ⅱ. Extreme-Environment Performance: Data-Driven Survival
