XLPE + PE
6-35 kV power cable with copper conductors, XLPE insulation and PE sheath
PvP is a medium-voltage power cable with a copper conductor, cross-linked polyethylene (XLPE) insulation and an outer sheath of polyethylene (PE). The main difference from PvV is the PE outer sheath instead of PVC. PE offers better moisture resistance and mechanical strength and is suitable for installation in high-humidity conditions. Designation breakdown: Pv – XLPE insulation, P – PE sheath.
Sizes for 6/10 kV. 3.6/6, 8.7/15, 12/20 and 18/30 kV versions are also produced.

PvP is a version of PvV with a polyethylene outer sheath instead of PVC. The polyethylene sheath performs better in terms of moisture resistance, mechanical strength and chemical resistance, but worse in terms of fire safety (ordinary PE is a combustible material). It is used in conditions where moisture and mechanical loads matter more than fire-safety requirements: underground tunnels with standing water, installation in chemically aggressive environments, and operation in regions with high air humidity.
Versions with a reinforced polyethylene outer sheath (PvPu) are also produced – see the corresponding product pages.
