Shenghua 21/35kV Aluminum XLPE Cable KEMA-Certified Seismic-Resistant

Shenghua redefines grid resilience with its triple-core aluminum-conductor XLPE cables, engineered to deliver 90°C continuous power for mining, renewables, and seismic zones. Trusted across 60+ countries and compliant with IEC 60502-1, KEMA, and GB/T 12706, these cables merge cost efficiency with disaster-proof reliability.

• Triple-Shielded Safety Architecture
  • Conductor: Compact stranded aluminum (IEC 60228 Class 2) slashing installation costs by 40% vs. copper, with ultra-low resistance (0.0778Ω/km for 3×400mm²)
  • Insulation: Nano-modified XLPE rated for 90°C continuous, 250°C/5s short-circuit, and ozone/UV resistance--extending lifespan to 50+ years in coastal zones
  • Armor: Copper tape screen + FR-PVC sheath (IEC 60502 ST2) blocking EMI, critical for smart grids near sensitive electronics
• Extreme-Environment Resilience
  • Seismic Performance: Min. bending radius of 15× OD (multi-core) withstands soil heave in earthquake zones like Japan's bullet train tunnels
  • Fire Safety: FR-PVC sheath option reduces smoke opacity to <15% (IEC 61034), mandatory for tunnels and hospitals
• Efficiency Engineered for Heavy Loads
  • High-Current Capacity: 3×400mm² carries 500A underground (soil), powering copper smelters without derating
  • Energy Savings: Ultra-low conductor resistance cuts transmission losses by 15% vs. industry averages

• Rated voltage: 6/10kV Low Voltage
• Maximum Conductor Temperature:
  • Under normal conditions: 90°C
  • Emergency conditions: 130°C
  • Short circuit (no more than 5s): 250°C
• Min. Ambient Temp. 0°C, after installation and only when cable is in a fixed position
• Min. Bending Radius:
  • 20 x cable O.D for single core without armor
  • 15 x cable O.D for multi core without armor
  • 15 x cable O.D for single core with armor
  • 12 x cable O.D for multi core with armor

We are capable of meeting the strictest delivery schedules according to per purchase order. Meeting the deadline is always the top priority as any delay in the delivery of cable can contribute to overall project delay and cost overrun.

Cable is supplied in wooden reels, corrugated boxes and coils. Cable ends are sealed with BOPP self-adhesive tape and non-hygroscopic sealing caps to protect the cable ends from moisture. The required marking shall be printed with a weather-proof material on the outsides of drum according to customer's requirement.
