I'm guessing you mean a brake /cable/ runs under your top
tube. ("Cable" is the common term for brake and
derailleur-control wires.)

If the washers are soft and rubbery, vaguely doughnut/torus
shaped, yes, these are commonly used to keep cable from
rattling. If the length of exposed cable is long, it
doesn't take so very much bouncing of the bike to get the
cable to bounce against the frame tubes. Brake cables
aren't all that stiff.

You're not wrong but we have found that using 'wire' and
'casing' specifically, separate from 'brake cable system' or
'gear cable system', helps when talking with consumers.
