Custom AWG 30 Gauge Copper Litz Wire Nylon Covered Stranded Wire
We can customize the enameled stranded wire that is more suitable for you according to the specific parameters you provide. As long as you know the operating frequency and RMS current required for your application, we can customize a stranded wire for your product.
Compared with single wire, Under the same conductor cross-sectional area, the stranded wire has a larger surface area. It can effectively inhibit the influence of the skin effect. Significantly improve the Q value of the coil.
Copper stranded wire not only has the strength and toughness of steel, but also has the good electrical conductivity and corrosion resistance of copper. Compared with copper single wire, it has the advantages of low density, high strength and low cost. It is a replacement product of traditional pure copper single wire.
