0.071mmx615 Nylon Serving Litz Wire Copper HF Transformer
Why choose nylon coating
Reduce "glue penetration" problem:
After winding transformers or inductors, they are typically impregnated with insulating varnish (such as varnish) for fixation and moisture protection. Without an outer layer, the insulating varnish can easily over-penetrate the Litz wire, filling the gaps between the strands. This increases the rigidity of the harness and, more importantly, alters the effective dielectric constant, thereby increasing distributed capacitance and reducing high-frequency performance. The nylon yarn layer forms a physical barrier, effectively limiting the over-penetration of the insulating varnish and thus maintaining the high-frequency characteristics of the Litz wire design.
Enhanced resistance to flexural fatigue:
Nylon yarn provides extra flexibility and elasticity, resulting in a more uniform stress distribution on the internal metal conductor during repeated bending, thus extending the lifespan of the wire.
Identification and Aesthetics:
Nylon yarns are typically available in various colors (such as white, yellow, blue, etc.) to distinguish different specifications and uses of the yarn, making production easier and improving the appearance of the product.
