Description
G-7 is a continuous filament glass cloth reinforced with silicone resin, forming a high-performance industrial laminate. This material exhibits excellent electrical insulation properties and is rated for the highest continuous operating temperature among industrial laminates, suitable for applications up to 180°C. G-7 laminates maintain low dielectric loss and high insulation resistance across a wide temperature range, even under humid conditions. The composite also demonstrates outstanding heat and arc resistance and is inherently self-extinguishing, providing enhanced safety in demanding environments.
Features
High Temperature Resistance: Continuous operation up to 180°C.
Excellent Electrical Insulation: Low dielectric loss and high insulation resistance, even under humid conditions.
Heat & Arc Resistant: Outstanding performance under thermal and electrical stress.
Self-Extinguishing: Provides enhanced fire safety.
Mechanical Strength: Strong and dimensionally stable, resistant to vibration and impact.
Reliable in Harsh Environments: Maintains performance under extreme conditions over long periods.
Applications
Aerospace Components: High-temperature insulation and structural parts.
Power Generation Equipment: Transformers, switchgear, and electrical panels.
Heavy Machinery: Insulating parts exposed to heat, vibration, and mechanical stress.
High-Voltage Electrical Systems: Reliable insulation in demanding environments.
Industrial Electrical Insulation: Bushings, spacers, washers, and other critical insulation components.
