Product Description
LE-9265/LH-9265: High Tg UL 94 V-0 Epoxy for HV Insulators & Bushings
Modified cycloaliphatic epoxy resin system engineered for high-voltage insulators, bushings, and contact boxes (12-40.5 kV). Combining UL 94 V-0 flame resistance, extreme weather durability, and high thermal stability (Tg >150°C), this unfilled liquid resin delivers void-free insulation for outdoor power infrastructure.
Key Features & Benefits
| Property | Advantage |
|---|---|
| Weather Resistance | Withstands UV, humidity, and pollution - ideal for outdoor bushings |
| Flame Safety | UL 94 V-0 certified - prevents fire propagation in electrical faults |
| Thermal Performance | High Tg (>150°C) + thermal shock resistance - stable under load cycles |
| Electrical Integrity | CTI >600 V, high dielectric strength - resists tracking/arcing |
| Processing Flexibility | APG or vacuum casting - integrates with existing production lines |
| Long-Term Reliability | Resists cracking, hydrolysis, and chemical corrosion |
Applications
- 12-40.5 kV switchgear: Contact boxes, cable terminations
- Outdoor bushings & insulators
- Transformer bushings and surge arresters
- Railway/utility power distribution insulation
