What is the American term for what the Aussies and/or Kiwis call figure 8 wire? I have googled it, but still don't get it.

Is it twisted pair?

Thanks.

Darn senior moments! Can't think of the word.
Something like, "aerial cable".

Mechanical support provided by a steel wire that holds up a signal wire across distances through the air.
The signal wire that I'm used to is coax.

Here's a sentence from the article I am reading.

"Where the Controller is mounted inside a cabinet or other dark place, the LDR can be mounted using a length of figure-8 wire in a position where it will be exposed to ambient light."

I should have included the sentence in my first post.

In my searching, I see that the support wire can be attached to just about any kind of cable. Twisted pair, coax, multi-pair, etc.

This is the first time I have seen the term "figure-8 wire".

I guess I would call it "twisted pair single-strand hook-up wire".

It's, "messenger wire" that I heard so long ago.

I'm thinking, ask any cable TV or internet service installer what he calls the wire from the pole to the house. He will probably call it a, "drop" and you will still be without the proper word. :D

I would agree with MrChips that it's probably twisted-pair wire to reduce interference signal pickup such as from the AC mains.

My Google search appears to show some different meanings for the term.

One such meaning is parallel conductors molded together, such that a transverse cut looks like a figure 8. Speaker cables are one such use. There are also multi-conductor cables in a figure 8 format.

Another meaning has been alluded to here in. It refers to a set of conductors in one cable molded to a second (in a figure 8 pattern) which contains a steel cable used to support the conductors.

I found a third, but likely non-relevant usage which seems to appear from Australia or New Zealand. This is a connector used to tightly connect fencing sections for agricultural applications.

I thought Figure 8 wire was this kind of stuff



like bell wire or speaker cable, called fig. 8 because of it's cross-section
