Is it normal for the shield to be green? or is this corrosion?

It doesn't look like corrosion to me, more likely it's some kind of glue or something.. Either way it's not looking too healthy in that state, is it still working? If you have a multimeter there you could give it a test.

Thank you so much for your answer. That picture was actually taken off this site . My cable doesn't look ad bad as that one but that picture was the only one showing the green stuff on the shield(I can't find more than that picture to assume it's normal on every adaptor ). I left my laptop charging and when I came back I found the insulation next to it . It seems like the insulation crackle and it starting falling off in pieces . The hole is about 1/4 -1/2 of an inch . I noticed in that section of the wire, that the insulation is harder than the rest of the wire and I know the hole might get bigger. The reason I asked the question: if it is normal , i will use a heat shrink . If it's corrosion then I was going to say bye bye to $80.

Thank you so much for your help.

Save the money and try the heat shrink! That's what I would be doing too. As long as the internal wires (under the metal shielding) are still good then it will be okay. It might be a good idea to double up on the heat shrink too, the more rigidity the better! You're welcome, please vote up if you find this helpful!

Be careful here! You can damage your systems charging logic if the wiring shorts out. I would recommend replacing the charger its a lot cheaper than replacing the logic board.

It sure looks like cupric chloride corrosion to me.

It isn't though because it's not copper.. Only copper corrodes green ;)

Rub it and if it comes off like a powder, taste it. I don't know what the metal is but I've certainly seen the same color of corrosion on liquid damaged logic boards. Look!

Do a Google search for images and "corrosion on liquid damged logic boards"

Go ahead and cover it with heatshrink, do not "say bye to $80". I saw a similar case of "green shield wire", it was caused by plasticiser oozed from insulation. Do not worry about it, likely it is not a risk, unless you can feel the wire getting warm (which indicates reduced conductance). One might wipe the green area in a paper towel, to remove some of that yucky plasticiser, before re-insulating it.
