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
