Product Description

Outdoor Epoxy Resin | UV-Resistant | Low-Shrinkage | HV Insulation (10-66kV)

Product Attributes

Thermal Class	F
Adhesion	Strong

Product Description

The LE-8216F/LH-8216F is an epoxy resin system engineered for medium/high-voltage electrical insulation (10-66kV). Featuring a modified weather-resistant anhydride hardener (LH-8216F) and low-shrinkage formulation, it delivers exceptional dimensional stability, superior arc resistance, and HB flammability rating. Ideal for vacuum-cast dry-type transformers, CTs/VTs, and critical insulation components.

Key Features & Advantages

Cyclic Aliphatic Epoxy Resin	Superior weather resistance + UV stability
Low Curing Shrinkage (0.9-1.1%)	Precision dimensions for complex HV parts
Thermal Class B (IEC 60085)	Reliable performance up to 130°C
Vacuum Casting Optimized	Seamless integration with existing production
High Dielectric Strength	>25 kV/mm (1mm, IEC 60243-1)
Low Water Absorption	0.08-0.15% (100°C/60min) for humid environments
Solvent-Free + Low VOC	Eco-friendly processing

Applications

Built for high-voltage electrical insulation:

Dry-type transformers
Current/voltage transformers (10-66kV)
Bushings, insulators, switchgear
Encapsulation of sensors & relays
Grid infrastructure components

Frequently Asked Questions (FAQ)

Q1: What makes LE-8216F suitable for outdoor HV applications?

A: Its cyclic aliphatic structure provides inherent UV/weather resistance, while low water absorption (0.08-0.15%) ensures stability in humid conditions.

Q2: What is the curing process?

A: Optimized for vacuum casting:
Pre-mix: 60-70°C/1-2h (100-300Pa)
Cure: 70-80°C/3-5h → 90-100°C/2-4h → Post-cure 130°C/12h

Q3: How does filler ratio affect properties?

A: Silica powder (300-360 pbw) enhances mechanical strength but must be uniformly dispersed. Adjust within range to balance viscosity vs. performance.

Q4: Is this system compatible with APG?

A: Designed for vacuum casting. For APG, consult Shanghai Wenyou for formulation adjustments.

Q5: What safety measures are critical?

A: Essential PPE: gloves, goggles, respirator. Maintain ventilation (3-5 air renewals/hour). Avoid skin contact--use barrier cream.
