Product details
1. This product is made by impregnating alkali-free glass fiber with epoxy resin under vacuum using a pultrusion process.
2. A key feature of the vacuum impregnation process is low partial discharge (<3pC).
3. Other advantages: Higher mechanical strength, superior dielectric strength and insulation performance, and lower leakage current compared to molded products. Lower water absorption.
4. More dimensionally stable. Flame retardant ratings and product colors can be designed according to customer needs.
