G'Day Allen and all,
Here in (Victoria at least) a catenary is also known to refer to the
strainer wire in an overhead cable.
I guess that this also fits in with the trolley, or railway overhead
system.
I quite often use a cable, usually a single pair of wires, but sometimes a
multi-pair cable, with a catenary wire moulded to it (them).
The purpose of the catenary is to take the strain of the wire between
poles. It is usually made of a thick (by comparison with the conductors)
steel wire, and is peeled back to allow the cable to hang without strain,
while the steel wire is the strainer.
Cheers
Rod
