Moisture-resistant pultruded rods for outdoor and switchgear duty.
Machinable phenolic rods for mechanical insulating parts.
Fish-paper rods for arc-facing and formed insulator parts.
Hardwood dowels and coffin sticks for fixtures and forming.
Straightness depends on diameter and length. For typical switchgear operating rods we hold runout to a few tenths of a millimeter over the length; confirm the number against your drawing.
Epoxy glass (ECR) resists moisture better and holds dimensions outdoors. GPO-3 tracks well but is usually specified for indoor enclosures. We will match the grade to the environment.
Thin-wall vulcanized fiber parts of Insulation Rods in Vulcanized Fiber, Epoxy Glass are typically held to ±0.05 mm on ID and OD. Knurl pitch, major and minor diameter and position come under review per drawing, with capability confirmed against your print instead of a published blanket claim.
No. For arc-facing duty on Insulation Rods in Vulcanized Fiber, Epoxy Glass use ceramic-filled epoxy glass, melamine or a synthetic arc-quenching composite. Vulcanized fiber suits non-arc-facing mechanical bodies and end caps.
Each batch of Insulation Rods in Vulcanized Fiber, Epoxy Glass is traceable to its incoming material certificate. Your quality plan can call for the material COA, first-article inspection, in-process checks and final inspection reports, which we supply on request.
For Insulation Rods in Vulcanized Fiber, Epoxy Glass, 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.
