Coaxial cable
A centre conductor drawn within a concentric outer conductor, used for RF, video and some high-frequency measurement leads.

IEEE / ANSI · W
ANSI/IEEE coaxial cable symbol
IEEE-oriented coaxial cable drawn as a centre conductor with a surrounding outer conductor that terminates at each end.
In plain English
What does ANSI/IEEE coaxial cable mean?
IEEE-oriented drawings represent coaxial cable with a centre line enclosed by an outer conductor outline, often with the outer conductor brought out to a ground or connector shell at the ends. The convention is used on communications, metering time-sync and RF schematics in US-practice drawing sets.
A simple example
This illustration explains the idea and is not a certified IEEE graphic. The cable impedance and connector types must still be given in text. Where the outer conductor is grounded at both ends between buildings, check for ground loop and surge transfer issues.
What the drawings help you do
Read connector and impedance notes at each end. Check outer conductor grounding at building entries. The ANSI coaxial form has a current-carrying outer conductor; the ANSI shielded conductor form has a screen only.

- Terminal
- An identified point where a conductor connects.
- Schematic
- A drawing showing function and connections rather than physical appearance.

How to read it
- Read connector and impedance notes at each end.
- Check outer conductor grounding at building entries.
Information to show or reference
- State cable type or impedance.
- Name connectors at each end.
- Show outer conductor grounding.
A distinction that matters
The ANSI coaxial form has a current-carrying outer conductor; the ANSI shielded conductor form has a screen only.
