WELLELE aramid paper tubing is a wound electrical-insulation sleeve for motors, transformers, coils and industrial electrical components where an aramid-paper construction is permitted. Material grade and source, paper thickness, layers, overlap, ID, OD, wall, length, electrical duty, temperature and environmental exposure are confirmed for each project and documented on the quotation or approved drawing.
• Aramid paper grade and source confirmed on the quotation
• ID, OD, wall, overlap, layers and length confirmed on the approved drawing
• Electrical, thermal and environmental requirements reviewed for the actual application
• Required traceability and finished-tube documents agreed before order acceptance
Choose aramid paper tubing when the design permits a paper-based aramid insulation sleeve and the material identity, construction and finished-tube requirements can be confirmed for the project.
| Review field | What to confirm |
|---|---|
| Material identity | Paper grade, source and required traceability |
| Construction | Paper thickness, layers, overlap and winding direction |
| Dimensions | ID, OD, wall, length, tolerance and roundness requirement |
| Application | Electrical duty, temperature exposure, environment and assembly method |
| Approval | Drawing, inspection method, acceptance criteria and required documents |
A named brand or grade must not be substituted without customer or design-authority approval.
| Parameter | Project information required | Confirmation |
|---|---|---|
| Material | Aramid paper grade, source and thickness | Quotation and traceability requirement |
| Construction | Layers, overlap and winding direction | Approved drawing |
| ID / OD / wall | Target dimensions, units and tolerances | Approved drawing and inspection method |
| Length | Cut length, tolerance and cut-end requirement | Order specification |
| Electrical duty | Required value, duration and test method | Approved test plan |
| Temperature | Continuous or peak exposure and duration | Engineering review with supporting evidence |
| Environment | Oil, moisture, humidity, chemicals and assembly conditions | Application validation plan |
WELLELE can review custom material, ID, OD, wall thickness, cut length, tolerance, color, surface, winding construction, inspection, labeling and packaging. Sample and production lead times depend on material, tooling, size, tolerance, quantity and validation requirements.
For quotation, send the application, drawing or photo, dimensions, operating conditions, annual quantity and required documents. Quotes are based on material, construction, tolerance and volume.
Is aramid paper tube the same as Nomex tube?
No. Aramid paper tube is the broader product category. Nomex tubing should be made from an identified Nomex grade and supported by the relevant traceability. A general aramid paper tube should use its correct material description
When should I choose an aramid paper tube?
Choose it when the specification permits general or identified aramid insulation paper and does not require a particular Nomex grade. Confirm electrical duty, temperature, exposure, dimensions and material documents before approval.
Can base-paper data approve the finished tube?
No. Base-paper data are a reference for the material, but tube performance also depends on winding, overlap, wall build, cut end, moisture conditioning and the finished-tube test method.
What size range can be customized?
Aramid paper tubing can be reviewed at approximately 1-60 mm ID and 0.08-0.51 mm wall. The exact size depends on paper thickness, layers, overlap, roundness, length, tolerance and quantity.
Engineering recommendation
Select aramid paper tube from the complete component dimensions, operating conditions, manufacturing process and acceptance criteria. Use samples to confirm fit and function before volume production.
Can aramid paper tube replace Nomex tubing?
Only when the customer specification and design authority allow the material change and the selected aramid paper and finished tube meet the electrical, thermal, dimensional and environmental requirements. It should not be presented as an automatic equivalent
