The LE-9518/LH-9518 Outdoor Epoxy Resin System is a premium two-component, non-premixed solution engineered for demanding outdoor electrical insulation applications. Designed for both Automatic Pressure Gelation (APG) and Vacuum Casting processes, this hot-curing epoxy resin delivers exceptional resistance to UV radiation, thermal shock, and environmental stress cracking. Ideal for medium-to-high voltage components like insulators, current transformers (CT), and voltage transformers (VT), it ensures long-term reliability in harsh conditions.
