I am having some issues with a PVC coated steel cable. The PVC often strips when used with a pulley.
I wanted to know why this may be happening and possible solutions for it.

The pvc coating is designed for cables in the open as a protection from dust, the elements etc.
If the pvc coated cable is going over a pulley then the pvc coating is subjected to crushing and tearing forces that exceed its design parameters.
You likely are using the wrong cable or using a cable outside of its designed use.
Consider other solutions ie different cables or a different design of mechanism, difficult to have any suggestions as your question lacks any useful detail.

The steel elastic limit is over 0,5% strain ( depending on strength) while the plastic goes into plastic strain at lower levels . So the plastic is failing in fatigue while the steel in only in the elastic strain range. – blacksmith37 Oct 14 '22 at 14:58
