High Light 99.8% Al2O3 High Alumina CeramicMetallized High Alumina CeramicHigh Whiteness Metallized Ceramics
99.8% High Alumina Ceramic for Electrical Insulation | High-Voltage Switchgear & GIS Components
Product Description
99.8% Al2O3 metallized ceramics for high-voltage insulation (126kV-1000kV). Ultra-white, low sodium content, optimized for SF6 circuit breakers & GIS. Custom formulations available.
Engineered for critical high-voltage applications, our 99.8% Al2O3 alumina ceramics provide superior electrical insulation and mechanical stability in demanding environments from 126kV to 1000kV systems. These ultra-white, low-sodium ceramics are specifically formulated for SF6 circuit breakers, GIS insulation, and epoxy resin casting systems.
Key Electrical Insulation Properties
  • Ultra-High Purity: 99.8% Al2O3 content with controlled impurity levels (Na₂O ≤ 0.20%)
  • Superior Dielectric Performance: Low conductivity (40-100 μS/cm) ensures reliable insulation
  • Optimized Processing: Controlled viscosity (3000 cp) and pot life for seamless epoxy resin integration
  • Precision Engineering: Tight particle size distribution (D50: 3-22μm) for consistent performance
Technical Specifications - Electrical Grade Alumina
Parameter ALF-02 Series ALF-03 Series ALF-09/10 Series Unit
