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
