Product Description

The LE-9215/LH-9215 is a high-performance epoxy system for medium/high-voltage electrical insulation (12-40.5kV). Featuring modified BPA epoxy resin (LE-9215) and anhydride hardener (LH-9215), it delivers exceptional thermal shock resistance, superior dielectric strength, and H-class thermal endurance (180°C). Optimized for vacuum casting and APG processes in contact boxes, insulators, and switchgear.

Key Features & Advantages
Modified BPA Epoxy + Anhydride Hardener High mechanical strength + thermal stability
Adjustable Silica Filler (300-400 pbw) Customizable viscosity/performance balance
Thermal Class H (IEC 60085) Reliable operation up to 180°C
Dual-Process Compatibility Seamless APG or vacuum casting integration
Low Curing Shrinkage (0.8-1.0%) Precision dimensional stability
HB Flammability Rating (UL94) Enhanced fire safety for electrical components
High Arc Resistance 181-198 sec (IEC 61621)
Applications

Built for critical HV insulation:

  • 12-40.5kV contact boxes & insulators
  • Switchgear components
  • Current/voltage transformers
  • Encapsulation of relays & sensors
  • Grid infrastructure protection devices

Frequently Asked Questions (FAQ)
Q1: What's the optimal silica filler ratio?
A: Adjust between 300-400 pbw - higher ratios enhance strength but increase viscosity.
Q2: How does this system handle thermal cycling?
A: Excellent thermal shock resistance due to low shrinkage (0.8-1.0%) and high Tg (105-120°C).
Q3: What curing process is recommended?

A: Vacuum Casting: Cure @70-80°C/3-5h -> 90-100°C/2-4h -> Post-cure 130°C/12h

APG: Post-cure @130-150°C/10-12h after molding.

Q4: Is color customization possible?
A: Yes! LC series color pastes can be added (3 pbw recommended).
Q5: Why choose HB flammability rating?
A: HB classification balances safety and cost for 12-40.5kV indoor applications.
