In what scenarios is PVC insulation still advantageous over XLPE?

While XLPE is technologically superior, PVC (Polyvinyl Chloride) remains a cost-effective solution for low-voltage applications ($0.6/1kV$) where high temperature is not a factor. PVC is more flexible, easier to strip during installation, and possesses inherent flame-retardant properties. It is ideal for indoor wiring, fixed installations in dry environments, and projects with strict budget constraints.
