Product Description

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.

Embedded Poles: Ensures structural integrity in coastal/industrial zones.
Renewable Energy Components: Wind turbine sensors, solar farm switchgear.

FAQ

Q: What certifications does this epoxy system hold?

A: Complies with IEC standards for outdoor electrical insulation (custom certifications available).

Q: Can filler be added?

A: Yes, silica fillers (e.g., 300-400 phr) enhance mechanical strength.

Q: Is it suitable for salt-heavy environments?

A: Yes, exceptional corrosion and salt-fog resistance.

Q: Minimum order quantity (MOQ)?

A: 10KG (20/220/1200KG drum options).
