G7 Electrical Insulation Sheet from SAM Composites India Pvt. Ltd. is made from NEMA Grade G-7 glass fabric reinforced with a silicone resin binder. It keeps its electrical and mechanical properties at temperatures up to 250°C and resists electrical arcing, which makes it a dependable choice where epoxy laminates reach their thermal limit. We supply it as pure white sheets in standard and cut-to-size formats for industrial buyers and OEMs.
Where a design needs insulation that stays stable in sustained heat, G7 Electrical Insulation Sheet is an ideal option. Its silicone binder gives it excellent thermal resistance and arc resistance, while the glass fabric reinforcement provides the mechanical strength needed for structural insulating parts. Every sheet is inspected before dispatch, and we also cut and machine it to your drawings.
G7 Electrical Insulation Sheet is commonly specified for electric furnace insulation, circuit breaker parts, switchboard panels and arc barriers, and for any assembly where the operating temperature is too high for standard epoxy glass laminate. Sheets can be supplied as standard sizes or fabricated into parts to your drawings.
Our units are divided into various dedicated and independent departments.
