Advantages:
  • High Dielectric Strength: ≥14.2 kV/mm at 90°C in oil with low permittivity (≤5.5/50Hz), ensuring reliable insulation and low loss.
  • Durable & Strong: ≥1.8 g/cm³ density and robust structure for long-term mechanical reliability.
  • Smooth Surface: Defect-free finish prevents partial discharge and simplifies installation.

Applications:

  • Ideal for Transformer Insulation: Combines exceptional parallel and perpendicular dielectric strength for reliable internal insulation.
  • Critical for Switchgear Applications: Offers proven mechanical durability and impact resistance in high-stress environments.
  • Essential for Busbar Supports: Delivers stable power distribution with low and consistent permittivity.
