LE-8516L/LH-8516L: Ultra-Low Viscosity Epoxy System for Void-Free MV Transformer Potting

Cycloaliphatic Resin + Anhydride Hardener for Precision CT/PT Encapsulation

Product Overview

LE-8516L epoxy resin and LH-8516L hardener deliver ultra-low viscosity (<500cPs mixed) for flawless void-free encapsulation of MV current/voltage transformers. Engineered to penetrate micron-scale gaps in densely wound coils, this system ensures partial discharge <5pC and compliance with IEEE C57.13 accuracy standards.

Critical Performance Advantages

Property Performance
Void Elimination <0.1% microvoids • Prevents electrical treeing
Electrical Integrity Volume resistivity >1E15 Ω·cm • DF <0.01 @50Hz
Thermal Management Conductivity >0.5 W/mK • Tg >110°C
Process Efficiency 5X deeper penetration vs standard epoxies

Applications

  • Instrument Transformers: CTs/PTs (15-36kV)

  • MV Switchgear Components

  • High-Voltage Insulators & Bushings

  • Precision Electronics Encapsulation

Optimized Processing

Method Key Benefit
Vacuum Gravity Casting Bubble-free impregnation of cellulose barriers
Automated Potting Systems Consistent results for high-volume production
Compatible with existing manufacturing setups

Colorant LC Series Paste As needed

Certified Performance Data

Parameter Value Standard
Mixed Viscosity 450-480 cPs ASTM D2196
Partial Discharge <3 pC @ 1.5Ur IEC 60270
Flexural Strength 105 MPa ISO 178
Thermal Shock Passes 500 cycles (-40°C↔125°C) IEC 60068-2-14

Why This System?

  • Precision Reliability: Maintains 0.2% metering accuracy in CTs/PTs

  • Short-Circuit Resilience: Withstands 50kA/3s mechanical stress

  • UV/Environment Proof: Cycloaliphatic chemistry resists yellowing

  • Faster Processing: Accelerator reduces gel time by 35%

The Gold Standard for HV Instrument Transformers – Trusted by global manufacturers for mission-critical grid components where dielectric perfection and long-term stability are non-negotiable.
