Brief: Discover LE-9204/LH-9204, a low-viscosity flame-retardant epoxy system designed for void-free impregnation of transformer coils and high-voltage bushings. With UL 94 V-0 certification, it ensures deep penetration, eliminates air pockets, and enhances dielectric strength. Ideal for VPI, APG, and vacuum casting processes in dry-type transformers and switchgear up to 40.5 kV.
Related Product Features:
  • Ultra-low viscosity for deep penetration into coil windings, ensuring void-free insulation.
  • UL 94 V-0 certified for flame safety in dry-type transformers and indoor switchgear.
  • Withstands over 1,000 thermal shock cycles (-40°C to +150°C) for thermal resilience.
  • High CTI (>600 V) and dielectric strength (>18 kV/mm) for superior electrical integrity.
  • Compatible with VPI, APG, and vacuum gravity casting for process flexibility.
  • Customizable with LF-630 flexibilizer (0-20 pbw) to reduce brittleness and stress.
  • Accelerated curing with LZ-622 for rapid production cycles.
  • Meets IEEE C57.12.01 standards for dry-type transformers, ensuring industrial compliance.
FAQS:
  • What is the UL 94 rating of LE-9204/LH-9204 epoxy?
    LE-9204/LH-9204 epoxy is UL 94 V-0 certified, making it highly flame-retardant and suitable for indoor electrical equipment.
  • What applications is this epoxy system suitable for?
    This epoxy is ideal for dry-type transformers, medium-voltage switchgear up to 40.5 kV, bushings, insulators, sensor coils, and PCB insulation barriers.
  • How does the low viscosity of LE-9204/LH-9204 benefit transformer coil impregnation?
    The ultra-low viscosity (<500 mPa*s) ensures deep penetration into complex winding structures, eliminating air pockets and preventing partial discharge for enhanced dielectric strength.
