Description
The G-7 Silicone Glass Rods are designed for high-performance in demanding environments. Made from a robust combination of glass fibers and silicone resin, they provide excellent electrical insulation, mechanical strength, and heat resistance. With a maximum operating temperature of 180°C, these rods maintain their structural integrity even under high-stress conditions, making them reliable for long-term industrial use.
Features
Outstanding electrical insulation performance under both dry and humid conditions
Exceptional thermal stability and high arc resistance for demanding environments
Self-extinguishing and flame retardant, meeting safety standards
High dielectric strength with minimal electrical losses at elevated temperatures
Composed of glass cloth reinforced silicone with natural cream-to-white coloration
Applications
Electrical insulation for transformers, switchgear, and other high-voltage equipment
Thermal and electrical insulation in heating elements, appliances, and industrial equipment
High-temperature electronic components where low dielectric loss is critical
Electrical systems operating under both humid and dry conditions
Applications requiring reliable insulation and flame-retardant performance in harsh environments
