The FR4 and G10 Epoxy Tube is a high-performance industrial material crafted from woven glass fiber fabric bonded with epoxy resin under high pressure and temperature. This process creates a composite tube renowned for its exceptional electrical insulation properties, outstanding mechanical strength, and excellent thermal stability. It is engineered to perform reliably in demanding electrical, electronic, and structural applications.

Key Features & Advantages:

Superior Electrical Insulation: Excellent dielectric properties make it ideal for high-voltage environments.

Exceptional Mechanical Strength: High rigidity and durability for demanding structural uses.

Wide Thermal Performance:

Standard operating range: -40°C to +70°C

With specialized high-temp resin: withstands over 200°C

Inherently flame-retardant (FR4 grade)

Low-Friction, High-Efficiency Bore: The exceptionally smooth inner wall boasts a friction coefficient (n=0.0084) significantly lower than concrete (0.014) or cast iron (0.013) pipes, enabling superior flow characteristics and transport efficiency.

Our epoxy resin fiberglass tubes are manufactured using vacuum casting technology within a controlled cleanroom environment, ensuring superior performance and exceptional product reliability.

These epoxyglass insulation tubes are extensively utilized in:

High-Voltage Electrical Equipment: Ideal for components in circuit breakers, isolation switches, and earthing switches, suitable for voltage levels ranging from 35kV to 1100kV.

Industrial Pipeline Systems: Widely applied in demanding pipeline applications, including waste lines, petrochemical transfer lines, and tank connection systems.
