Protecting Sensitive CT/PT Coils | Vibration Resistant RT Cure Potting Compound
LW-8224A/B: Vibration-Resistant Epoxy for Outdoor CT/VT Transformers - 12-40.5kV Crack-Proof Encapsulation
Prefilled BPA Resin | Thermal Shock Stability | Room Temp Cure
Engineered for outdoor CT/VT transformers, this prefilled Bisphenol-A epoxy system delivers vibration-resistant potting for 12-40.5kV coils exposed to extreme weather. LW-8224A resin + LW-8224B anhydride hardener provide crack-resistant encapsulation protecting delicate windings from mechanical stress, temperature swings (-40°C to 155°C), and environmental degradation.
Critical Advantages
  • Vibration Damping: Shields sensitive CT/PT coils from operational stress
  • Outdoor Endurance: Superior UV/weather resistance for transformers
  • Crack Resistance: Withstands thermal cycling in low/high temperature conditions
  • Prefilled System: Ready-to-use precision formulation
  • Energy-Efficient: Room temperature cure eliminates oven dependency
Applications
Voltage Class Components
12-40.5kV Systems Current/Voltage Transformers (CT/VT), Dry-Type Transformers
Medium/High Voltage Bushings, Insulators, Switchgear
Processing Methods
Method Key Benefit
Vacuum Gravity Casting Bubble-free encapsulation for intricate coils
APG (Automated Pressure Gelation) High-volume production of vibration-resistant parts

Hardener LW-8224B 100 pbw
Colorant LC-Series* 3 pbw
*Add for UV-stable pigmentation in outdoor applications
Technical Superiority for Demanding Environments
This electrical-grade potting compound combines prefilled precision with outdoor durability. Its optimized viscosity ensures complete gap filling for CT/VT windings, while room temperature curing slashes production costs. Validated for 12-40.5kV transformers, it delivers unmatched mechanical-electrical stability under thermal shock, vibration, and moisture exposure - ideal for dry-type transformers in renewable energy grids and substations.
