RG-213 Cable with electric strained wire as metallic shield of Coaxial cable
$begingroup$
I'm using RG-213 coaxial cable for two-way ham radio communication. But due to weather conditions, the metallic shield of my coaxial cable (RG-213) become rusty and carbonated.
If I use copper electrical cable 3/.029 as metallic shield with aforesaid (rusty metallic shield ) Coaxial Cable, what will be the result? Will it be the best solution for my damage metallic shield coaxial cable or not? Can i get the best two way communication with this method?

You cannot repair a coaxial cable by wrapping or replacing the outer conductor (shield) with ordinary wire. The shape of the shield is critical to its functioning (determining the characteristic impedance) and the different impedance created by using differently shaped conductors will lead to reduced performance, and possibly damage your transmitter if it does not have high-SWR protection.
Weather-damaged coaxial cable should be replaced with new coaxial cable. Be sure to apply suitable sealing tape (self-amalgamating tape) to the end connectors after tightening them down if they will be exposed to moisture.
The one thing you can do for damaged cable is to cut off the damaged section and install a connector (a proper coaxial connector, not a splice) to join it to a new length. However, this is not a good idea for outdoor installations since it introduces more places for water to get in.
$endgroup$

That impedance bump has a minuscule effect below 50 Mhz, as it's only a tiny fraction of the wavelength.

@MikeWaters I understood the question as asking about replacing a long length of shield with other wire. We don't know what the length is (I removed "bump" from the answer to improve it), and the question isn't about HF specifically either.
