AI Overview
CNC machined G10 transformer bobbins (or FR4/G11) are high-strength, electrical-grade fiberglass epoxy laminates typically fabricated through CNC milling and turning for superior insulation and structural rigidity. They are favored for dry-type, high-voltage, or high-temperature transformers where moisture resistance and zero contamination are required.
Key Features of G10/FR4 Bobbins
- Material: Woven fiberglass cloth impregnated with epoxy resin, cured under high pressure.
