Description
High Mechanical Strength Anti-Cracking Epoxy Casting Resin for Thermal Cycling Switchgear Insulators
LW-9229A/B: Crack-Resistant Room Temp Cure Epoxy for 10-35kV CT/PT Insulation & Outdoor Encapsulation
UL-Certified | Pre-Mixed Fillers | Superior Dielectric Strength

Engineered for outdoor electrical insulation in Current Transformers (CT) and Potential Transformers (PT), this modified BPA epoxy system delivers crack-resistant encapsulation for 10-35kV terminal posts, bushings, and transformer components. With pre-mixed fillers in both resin (LW-9229A) and hardener (LW-9229B), it ensures consistent thermal shock resistance and long-term durability in harsh environments.

Key Advantages
  • Crack Resistance: Withstands thermal cycling for outdoor applications
  • High Dielectric Strength: Critical for 10-35kV insulation systems
  • Pre-Mixed Fillers: Simplified processing, no weighing errors
  • Room Temperature Cure: Energy-efficient transformer manufacturing
  • Moisture & Chemical Resistance: Protects CT/PT units from environmental degradation
Applications

Ideal for:

  • 10-35kV sealed terminal posts
  • CT/PT transformer potting & coil encapsulation
  • Outdoor bushings, insulators, switchgear
  • High-voltage electrical insulation components
