Southwire's THHN and THWN is a multi-purpose building wire used in conduit and cable trays for service, feeders and branch circuits in commercial and industrial applications. It is also used as a conductor in NM-B, UF-B, SER, SEU and MC. Southwire's THHN is rated for 600-Volt and has a heat capacity of up to 90°C.

对应的英文是：Four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method。 本文中，我们将会学习何时以及为啥要使用四线测电阻。 要想理解四线测电阻得先理解两线测电阻，两线测电阻时电路图如下： 万用表测量电阻的步骤如下： 流入到待测电阻的电流大小与万用表的量程相关。 量程越大，输出电流越小，反之，量程越小，输出电流越大。 对于非常低的量程挡位，输出电流可能是 1 毫安或者几个毫安，更大的挡位，输出电流会更小。 当待测电阻的阻 …

2024年2月3日 · 4 wire cables, comprised of four insulated conductors, are a pivotal component in contemporary electrical applications, serving a broad spectrum of electrical and data transmission needs. Their versatility is matched by their capacity to enhance safety and operational efficiency.

A 4-wire transmitter uses four wires: two for power supply and two for signal transmission. This configuration offers the highest signal accuracy because there is complete separation between power and signal wires.
