Product Description

High-purity 99.7% Al2O3 ceramic filler for SF6 gas-insulated switchgear. Provides excellent electrical insulation, high mechanical strength & optimized viscosity for epoxy casting.

TM-FA High-Purity Alumina Filler for High-Voltage Electrical Insulation

TM-FA is a specialized high-purity alumina (Al₂O₃ ≥99.7%) powder engineered as a functional filler for epoxy casting systems in high-voltage electrical equipment. It is designed to enhance the mechanical and insulating properties of insulation components used in SF6 gas-insulated switchgear (GIS) and other high-voltage applications.

Key Properties & Benefits

• Superior Electrical Insulation: Ensures high dielectric strength and reliable performance in demanding high-voltage environments.

• Enhanced Mechanical Strength: Contributes to the structural integrity and durability of cast epoxy insulation parts.

• Optimized Rheology: A carefully controlled particle size distribution and morphology ensure ideal viscosity (400-700 cP) for seamless processing and high packing volume during casting.

• High Purity & Reliability: Ultra-low impurity content (e.g., Na₂O ≤0.10%, Fe₂O₃ ≤0.03%) guarantees consistent performance and long-term stability.
