LE-8516L/LH-8516L: Ultra-Low Viscosity Epoxy System for Void-Free MV Transformer Potting

Cycloaliphatic Resin + Anhydride Hardener for Precision CT/PT Encapsulation

Product Overview

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.
