FIELD: electricity.
SUBSTANCE: high-voltage supply cable (HV) or superhigh-voltage supply cable is described. The cable includes conductor surrounded by at least one layer including polypropylene. Polypropylene includes nanosize fragments of catalyst, which source of origin is solid catalyst system. Nanosize fragments of catalyst have average size of particles d50 less than 1 mcm as measured by Coulter counter LS200 at indoor temperature with n-heptane as medium. Cable manufacturing method is also described.
EFFECT: manufacturing of cable with polypropylene having low electric conductivity.
