Cycloaliphatic Resin + Anhydride Hardener for Precision CT/PT Encapsulation
LE-8516L epoxy resin and LH-8516L hardener deliver ultra-low viscosity (<500cPs mixed) for flawless void-free encapsulation of MV current/voltage transformers. Engineered to penetrate micron-scale gaps in densely wound coils, this system ensures partial discharge <5pC and compliance with IEEE C57.13 accuracy standards.
| Property | Performance |
|---|---|
| Void Elimination | <0.1% microvoids • Prevents electrical treeing |
| Electrical Integrity | Volume resistivity >1E15 Ω·cm • DF <0.01 @50Hz |
| Thermal Management | Conductivity >0.5 W/mK • Tg >110°C |
| Process Efficiency | 5X deeper penetration vs standard epoxies |
