VVG-PNG(A) Cable for Stationary Electrical Installations

Cables are intended for transmission and distribution of electric power in stationary electrical engineering installations for nominal alternating voltage 0,66 and 1 kV nominal frequency 50Hz. For laying without limiting the difference in level along the route of laying, including vertical sections. For operation in electric networks of alternating voltage with earthed or insulated neutral, where the duration of operation is not limited by the difference of levels along the route of laying, including vertical sections.

neutral in which the duration of operation in single-phase short-circuit mode does not exceed 8 hours, and the total duration of operation in single-phase short-circuit mode does not exceed 8 hours. duration of operation in single-phase earth fault mode does not exceed 125 hours per year. For group laying in cable constructions of outdoor (open) electrical installations (cable overpasses, galleries, galleries, etc.), the total duration of operation in the mode of single-phase short circuit to earth does not exceed 125 hours per year.
