Frequently Asked Questions
Q What is the product model of this cloth-covered wire?
The product model is WM(L) (B)-0.20～1.25. It is produced by an extrusion process using flat copper or aluminum wire wrapped with 2–3 layers of polyester film and electrical non-woven fabric as the insulation layer.
Q What applications is this wire suitable for?
This wire is designed for manufacturing type reactors. Its multi-layer insulation construction provides excellent voltage resistance, making it ideal for demanding electromagnetic applications.
Q What size ranges are available for the flat wire and round wire?
For flat wire, thickness size A ranges from 0.80–5.60 mm and size B from 2.00–16.00 mm. For round wire, the diameter D ranges from 1.90–5.00 mm. Custom sizes outside these ranges are available upon request.
Q What are the resistivity requirements for the copper and aluminum conductors?
The aluminum wire must have a resistivity ≤ 0.02801 Ω·mm²/m at 20°C (per GB/T 55843-2009), while the copper wire must have a resistivity ≤ 0.01724 Ω·mm²/m at 20°C (per GB/T 55842-2009).
Q What are the dimensional tolerances for circular conductors?
Dimensional deviation varies by diameter: for 0.90 < d ≤ 2.50 mm it is +0.013; for 2.50 < d ≤ 3.00 mm it is +0.025; and for 3.00 < d ≤ 5.00 mm it is +1%d.
Q What is the minimum elongation requirement for circular conductors?
For circular conductors with a nominal diameter of 0.90 < d ≤ 2.50 mm, the minimum elongation is 15%. For conductors with a diameter of 2.50 < d ≤ 5.00 mm, the minimum elongation is 20%.
