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.

Key Features & Advantages

• Extreme Weather Resistance: Superior UV stability and thermal shock resilience (-40°C to 150°C).
• High Dielectric Performance: Critical for 35kV+ outdoor insulation systems.
• Dual-Process Compatibility: Optimized for APG (fast curing) and vacuum casting (precision molding).
• Low Volatility: Vapor pressure <0.01 Pa (resin) and 0.5 Pa (hardener) enhance workplace safety.
• Mechanical Robustness: Withstands high mechanical stress in power infrastructure.
