Epoxy Resin for Indoor High-Voltage Switchgear Bushings
Transformers Product Attributes
Product Description The LE-9219K/LH-9219K is a high-performance two-component epoxy resin system designed for medium/high-voltage electrical insulation (12-40.5 kV). Formulated with modified BPA epoxy resin (LE-9219K) and carboxylic anhydride hardener (LH-9219K), it delivers exceptional thermal shock resistance, superior crack resistance, and H-class thermal stability (IEC 60085). Ideal for vacuum casting or APG processes, it ensures reliability in critical indoor electrical components. Key Features & Advantages
Applications Perfect for insulating components in indoor high-voltage systems:
Key Performance Data Cured system: LE-9219K/LH-9219K/Silica powder = 100:100:350 @ 140°C/10h
Frequently Asked Questions (FAQ) Q1: What is the mix ratio for LE-9219K/LH-9219K? A: Standard ratio is 100:100 pbw (resin:hardener). Filler (silica
powder) added at 300-380 pbw. Q2: How should the hardener be stored? A: Store in sealed containers at 6-35°C. Avoid moisture exposure.
If crystallized, preheat to 70-80°C and stir before use. Q3: What curing process is recommended? A: Two options: Vacuum Casting: Cure 70-80°C/3-5h + 90-100°C/2-4h; Post-cure 130°C/12h. APG: Mold temp 130-160°C; Post-cure 130-150°C/10-12h. Q4: Is this system suitable for outdoor use? A: Designed for indoor electrical insulation only. Hydrophobicity
class HC1 (IEC TS 62073). Q5: What safety measures are required during handling? A: Mandatory: gloves, goggles, protective clothing. Use ventilation
(3-5 air renewals/hour). Avoid skin contact--wash immediately if
exposed. |
