Epoxy Glass Fiber Filament Wound Tubes
Customized composite insulation tubes engineered for high-voltage electrical applications where dielectric reliability, mechanical support and dimensional control are required together.
Designed as an insulation and load-bearing tube, not a general FRP pipe.
Continuous glass fiber and epoxy resin are filament wound and cured into a composite tube. The final construction is reviewed around voltage level, mechanical load, interface requirement, wall thickness and customer validation plan.
Electrical Insulation
Stable dielectric behavior for high-voltage equipment.
Low Porosity
Controlled wet-out and cure reduce internal defects.
Thermal Stability
Resin and Tg options selected around operating requirements.
Made to Drawing
OD, ID, wall thickness, length, machining, and interfaces.
