Download the PDF datasheet for this product family.
Wound to a fiber angle set by your load path, then machined to shape.
Standard and custom-wound fiberglass tubing for insulation and structure.
Machined casing, bushing and insulator shapes from wound epoxy glass.
Insulator inserts for PV and busbar terminal assemblies.
Bodies for current-limiting links, built to the clearing spec.
Composite motor-case tubing wound to pressure and thrust load.
Vulcanized-fiber backing discs for bonded abrasive wheels.
FR-4 is G10 with a flame-retardant brominated epoxy (UL 94 V-0). Mechanically and electrically they are close; FR-4 is specified when the part must self-extinguish. We stock both and machine to either grade.
Yes. Filament winding lets us set the glass angle to match hoop, axial or combined loading. Tell us the pressure or column load and we will propose the winding schedule.
Yes. We hold ±0.05 mm on ID/OD with CNC turning and grinding using diamond-coated tools to avoid delamination.
It has good arc resistance but is not arc-quenching. For direct arc contact, pair with ceramic-filled or synthetic arc-quenching composites.
Material COA, batch traceability, first-article and final inspection per your plan. Certificates comply with RoHS and REACH on request.
For G10 / G11 Epoxy Fiberglass Tubes, put the drawing, material grade, dimensions, tolerance and annual quantity in the enquiry. We match the grade, then respond with what we can manufacture and what it costs.
