Frequently Asked Questions
Q1
What is the product model of this cloth-covered wire, and what is it used for?
The product model is WM(L)(B)-0.20~1.25. It is primarily used for manufacturing type reactors, featuring 2–3 layers of polyester film and electrical non-woven fabric as insulation, offering excellent voltage resistance.
Q2
What are the available size ranges for flat and round cloth-covered wires?
For flat wire, thickness size A ranges from 0.80 to 5.60 mm, and size B ranges from 2.00 to 16.00 mm. For round wire, the diameter (D) ranges from 1.90 to 5.00 mm. Custom specifications beyond these ranges are available upon request.
Q3
What material standards do the copper and aluminum conductors comply with?
The aluminum wire meets GB/T 55843-2009, with a resistivity at 20°C of ≤ 0.02801 Ω·mm²/m. The copper wire complies with GB/T 55842-2009, with a resistivity at 20°C of ≤ 0.01724 Ω·mm²/m.
Q4
What are the dimensional tolerances for circular conductors?
For nominal diameters between 0.90 and 2.50 mm, the deviation is +0.013 mm. For 2.50 to 3.00 mm, the deviation is +0.025 mm. For diameters between 3.00 and 5.00 mm, the deviation is +1% of the nominal diameter.
Q5
What is the minimum elongation requirement for circular conductors?
For conductors with a nominal diameter between 0.90 and 2.50 mm, the minimum elongation is 15%. For diameters between 2.50 and 5.00 mm, the minimum elongation requirement increases to 20%.
Q6
