How coaxial cables work

Coaxial cable is divided into four layers from the inside to the outside: the central copper wire (single-strand solid wire or stranded wire), plastic insulator, mesh conductive layer and wire sheath. The central copper wire and the mesh-like conductive layer form a current loop. It is named because the central copper wire and the mesh conductive layer are in a coaxial relationship.

Coaxial cables conduct alternating current rather than direct current, which means that the direction of the current is reversed several times per second.

If a normal wire is used to transmit high-frequency currents, the wire acts as an antenna that emits radio outward, an effect that dissipates the power of the signal and reduces the received signal strength.

Coaxial cables are designed to solve this problem. The radio emitted by the central wire is isolated by the mesh conductive layer, which can control the emitted radio by grounding.

There is also a problem with coaxial cables, that is, if a certain section of the cable is squeezed or twisted, the distance between the central wire and the mesh conductive layer is not consistent, which will cause the internal radio waves to be blocked. reflected back to the source of the signal. This effect reduces the acceptable signal power.

To overcome this problem, a plastic insulator is added between the center wire and the mesh conductive layer to ensure a consistent distance between them. This also causes the cable to be relatively stiff and not easy to bend.
