Fiber Glass Laminates
Fiber glass laminates are widely used as electrical insulators with good dielectric strength, mechanical strength and thermal resistance, and are now an integral element in modern electrical equipment, transformers and industrial applications where durability and reliability are required for successful outcomes. ACC Insulations produces high performance fiber glass laminates that meet a wide range of electrical and industrial standards.
Our range includes NEMA standard grades such as G10, G11, FR4, and FR5. These glass cloth reinforced epoxy resins are engineered for Thermal Class F (155°C) and Class H (180°C) compliance, ensuring they remain structurally sound under high-voltage arcing and extreme thermal cycling.
What Are Fibre Glass Laminates?
Fiber glass laminates are composites made of sheets of glass fiber fabric bonded together with a thermosetting or curing resin (an epoxy or polyester resin) to form a dense, rigid, electrically insulative, structural material with excellent mechanical properties.

Frequently Asked Questions
Yes, which makes them suitable for high voltage insulation.
While both offer excellent dielectric properties, G11 laminates retain higher mechanical strength at elevated temperatures (up to 155°C - 180°C) compared to G10. G11 is preferred for high-load transformer spacers, while G10/FR4 is standard for electrical panels and terminal boards.
