Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

Coaxial cable

The coaxial cable symbol shows an inner conductor surrounded by a concentric outer conductor that forms the return path. Unlike a screened conductor, the outer conductor of a coaxial cable is part of the signal circuit and sets a defined characteristic impedance. It appears on antenna feeds, GPS time-sync leads to protection relays, video circuits and some partial-discharge sensor connections.

A distinction that matters

In coaxial cable the outer conductor carries return current; in a screened conductor the screen only intercepts interference.

IEC

Coaxial cable with earthed outer conductor

This form adds an earth connection to the outer conductor of a coaxial cable. On antenna systems the outer conductor is normally bonded to the building earth where it enters, often through a lightning arrester or earthing kit, and the drawing should show that bonding explicitly.

Form evidence

Coaxial pair with earthed outer conductor. Independent IEC-context combination of coaxial and earth forms; not certified IEC geometry.

A distinction that matters

Earthing the outer conductor sets its reference; it is not the same as a coaxial surge protector, which clamps the inner conductor.
