A Youtube account suspension is essentially the same as having your Youtube account Permanently disabled which means that the suspension of your Youtube account is permanent.
You can however appeal the decision of Youtube suspending your account and it can take up to 28 to 30 days to get a response back from Youtube about the account suspension.
After they make a decision it's permanent and they won't reply to any further responses to their decision.
So if you can't get your account reinstated the only thing you can really do is just create a new Youtube account and re upload videos except don't upload videos that violate copyright to avoid your new Youtube account from being suspended as well.
