Yesterday, my third clutch cable snapped

!!! Every year i replace one. Why is this happening? Can anyone know how to fix this annoying problem? BTW my gear box is working fine, no strange sound from it. I am easily changing gears. Even reverse is working fine. Is there a way to convert clutch with cable in hydraulic clutch? It is the problem with clutch pressure plate or clutch plate?
I had never experienced any other major problem with my 1.4 MPI Polo, except this one.
Please help
