COAX Cable is not used for audio feeds, Coax is for aerials

I thought that a Co-Axial cable was just a reference given to the type of cable that has a centre core surrounded by a braided outer sheath.

Indeed just like aerial cable . . . . .

. . . . . And also just like RCA cable  !!!     ::)

Whats the problem ?   :P

COAX Cable is not used for audio feeds, Coax is for aerials.

The main difference between screened and coax cable is the way the outer braid is either wrapped or woven, or in some cases solid braided, the latter two giving better line / transmission loss.

You could in fact use any cable, with mixed results, as long as you knew the impedance (dialectic spacing) and the cables velocity factor (wave propagation speed).

Coax Audio or Coax Digital Audio are just the name given to them because of the way the outer screen is woven.

The word Coaxial means "Having or mounted on a common axis."

When applied to the conductors of a cable it means only that. Coaxial cable is available in many different types, some suitable for audio, some suitable for video, some suitable for RF, some suitable for neither.

The electricity supply to my house comes in on a coaxial cable. Live on the centre conductor, neutral on the armoured outer. I wouldn't like to try connecting an aerial with it. ;)

I think you may have that wrong Kevin the supply to you house if not via overhead lines as in the countryside will be line conducter in the middle mineral sheath insulation with the outer conductor being both neutral and earth . as this is what is termed a T-N-C-S system

Correct. :y Neutral and earth are combined in such a system. It's still a coaxial cable though. ;)

i now understand what you are getting at, and i will accecpt that coaxial cable is 2 conductors running on a common axis however if you where to walk in to a electrical wholesellers and asked for coax cable you would be given airael cable not power cable

The Institute of Electrical Engineers would have a fit if you described the main feed to your house as co-ax!
The dictionary definition of co-ax may well be as posted earlier, however definitions of words vary according to use & trade.
