Frequently Asked Questions
Q What is the product model for this cloth-covered winding wire?
The product model is WM(L) (B)-0.20～1.25, covering a range of flat and round copper or aluminum conductor configurations.
Q What insulation materials are used in this winding wire?
The insulation layer consists of 2–3 layers of polyester film combined with electrical non-woven fabric, applied via an extrusion process, providing excellent voltage resistance.
Q What size ranges are available for flat and round conductor wires?
For flat wire, thickness A ranges from 0.80–5.60 mm and thickness B from 2.00–16.00 mm. For round wire, the nominal diameter D ranges from 1.90–5.00 mm. Custom sizes outside these ranges are available upon request.
Q What resistivity standards must the conductor materials meet?
Aluminum wire must meet GB/T 55843-2009 with resistivity ≤ 0.02801 Ω·mm²/m at 20°C. Copper wire must comply with GB/T 55842-2009 with resistivity ≤ 0.01724 Ω·mm²/m at 20°C.
Q What is this winding wire primarily used for?
This wire is specifically suitable for manufacturing type reactors, benefiting from its high voltage resistance and precise dimensional tolerances.
Q What elongation performance is required for circular conductors?
For diameters from 0.90 mm to 2.50 mm, the minimum elongation is 15%. For diameters from 2.50 mm to 5.00 mm, the minimum elongation required is 20%, ensuring flexibility during winding applications.
