Composite Fuse Tubes for Electrical Protection
Our composite fuse tubes combine two or more material layers to meet electrical, thermal and mechanical requirements that a single-material tube may not cover. Typical constructions use a functional inner liner with a reinforced glass-fiber/epoxy outer wall.
Compare composite tube constructions
| Product | Construction | Selection focus |
|---|---|---|
| Vulcanized fiber composite fiberglass tube | Vulcanized-fiber inner tube with glass/epoxy outer reinforcement | Fiber interface plus reinforced shell |
| Vulcanized fiber epoxy canvas tube | Fiber inner layer with epoxy-impregnated glass canvas | Machinable composite construction and drawing-based features |
| Ceramic wound fiberglass tube | Ceramic liner with wound glass/epoxy outer shell | High-temperature ceramic interface and structural reinforcement |
Key design inputs
- Inner-liner material, grade and required function
- Outer reinforcement, resin system and wall build
- ID, OD, length, concentricity and interface tolerances
- Rated voltage, interrupting duty, temperature and environmental exposure
- Machined ends, slots, holes and assembly interfaces
- Material certificates, inspection reports and validation methods
RFQ checklist
Send the finished drawing or sample, required inner and outer materials, dimensions, tolerances, electrical duty, temperature, quantity and test requirements. We will review layer compatibility, machining feasibility and inspection points before quoting.
For single-material alternatives, use the main fuse tubes selection guide or review our filament wound tube.
Frequently asked questions
What is a composite tube for fuse links?
It is a multi-material tube engineered for fuse-link service, combining insulation, arc performance and mechanical support in one component.
How do I select the right composite tube?
State the voltage class, fault current, inner/outer diameter and environment; the engineering team will match the material structure to the requirement.
