Electrical Insulation Board Class H Dependable Insulation For Electrical Applications

Product Description:

The Epoxy Glass Laminated Sheet utilizes specially treated non-alkali glass fiber cloth as the reinforcement substrate and high glass transition temperature (Tg) epoxy resin as the adhesive, manufactured through a hot-pressing process under high temperature and pressure. This material maintains excellent mechanical strength at elevated temperatures and demonstrates stable electrical performance under high humidity conditions. Rated as Class H heat-resistant insulation material, it is widely used in power generation equipment, high-voltage electrical apparatus, rail transportation, and electronic communication fields that demand high reliability.

Advantages:

• Exceptional Thermal Resistance and Mechanical Performance
  Utilizing high-Tg epoxy resin, it qualifies as a Class H insulation material.     It not only operates reliably under long-term high-temperature conditions but also maintains excellent mechanical strength and dimensional stability, resisting softening or deformation, making it suitable for high-temperature and high-load applications.
• Outstanding Electrical Insulation Stability
  With high dielectric strength and low dielectric loss, it demonstrates remarkable stability even in high-temperature and high-humidity environments, making it an ideal insulation material for high-voltage applications.
• Excellent Environmental Tolerance
  The dense structure of the epoxy resin system results in low water absorption, providing effective resistance to a wide range of chemicals, solvents, and oils.  This significantly extends its service life in harsh environments.
• Superior Machinability and Adaptability
  It offers excellent mechanical processability, allowing for easy fabrication into complex-shaped components.    This ensures convenient processing and strong adaptability.
