Help with electrical symbol

Dear all

I've come across this symbol on (most likely) korean electrical drawings, a wire(?) around other wires, sometimes connected to terminal, sometimes connected to ground.

Does anyone know what is this about?
please don't make assumptions, thank you

Is it simply denoting that those conductors are incorporated in the same cable ?

A 4 core cable with the shield/braid earthed at both ends, I assume

asabove ^^^. also looks to be an earthed metallic sheath.

I suspect it is an earthed screen encompassing a cable. This maybe functional in some cases and protective in others.

Out of interest what is the cable being used for or with?

Thank you all for your answers. It's probably this earth shield as you folks say.

FYI the drawing comes from a console with various electronics, for ship navigation. This symbol can be seen in almost all of the 30 pages.

It is purely and simply signifying that it is a multicore screened cable. The type of cable will need to be investigated as to the purpose it is being used for.
