Can I repair my 45W MagSafe 2 power adapter with a worn cable to avoid scrapping it all?

The insulation on my Apple power adapter cable has gradually worn away, exposing the internal wires. Over time, the adapter stopped working. Also, the part which connects to the charging port on the macbook is separated from the cable. I’d really prefer not to buy a new adapter, especially since I suspect the issue lies primarily with the cable, not the power brick itself. I’m exploring possible repair options—whether fixing the cable or replacing just the cable. If you’ve attempted a similar repair, especially in regions like Egypt (or anywhere where Apple-certified parts and services are harder to come by), I’d appreciate hearing your experience or recommendations. Is it possible to repair or replace the cable, or is buying a new adapter the only solution?
