TFN、TFFN、THHN或THWN电线

作者: Digi-Key 工程师 Patrick Glasser

这些类型的电线之间有什么区别,为什么我要使用其中一种,它有哪些优势?这些都是单芯导线,而它们对应的四个字母则表示这些导线通过的认证。这些电线之间的区别非常细微,但有些差异需要根据具体的应用进行考虑。

TFN (热塑性夹具尼龙)——一种用于固定装置的单芯实心导线。

TFFN (热塑性柔性夹具尼龙)——这种电线比TFN、THHN或THWN更柔韧,可用于需要柔韧性的夹具和应用。TFFN仅适用于16AWG-18AWG,并进行绞合以确保更好的柔韧性。

THHN (热塑性高耐热尼龙)——这种电线采用实心和多种绞合形式,且比TFN或TFFN具有更多的尺寸选择。此外,这种电线也比TFN或TFFN具有更好的耐热能力。

THWN (热塑性耐热耐水)——如果THHN电线同时列有THWN标记,则表示这种电线同时耐水,且可以在干燥和潮湿的地方使用。如果只标为THHN,则只能在干燥的地方使用。
