Thermoset composite materials offer several key benefits for use in high voltage transformers
As global energy demand soars, the need for advanced technology and materials to ensure efficient power transmission becomes crucial. With the rapid shift towards ultra-high voltage systems, engineers require materials and components they can trust.
Explore how Atlas Fibre’s thermoset composite parts, made from materials like G10, FR4 and GPO-3 are essential in power generation equipment like transformers, ensuring a reliable and continuous power supply.
Epoxy glass laminates are used for coil insulation, spacers, and structural components due to their high mechanical strength and electrical insulation properties. Paper phenolic and paper epoxy composites are also cost-effective options for insulating low-voltage, dry-service electrical equipment.
