Applying area and purpose
Cables are designed for transmission and distribution of electric energy in stationary electrical installations at a rated alternating voltage of 0.66 and 1 kV with a frequency of 50 Hz
Cables of the PPGNG (A) -HF, PPGENG (A) -HF, PvPGNG (A) -HF and PvPGENG (A) -HF cables are designed for group installation in rooms and cable structures in the absence of danger of mechanical damage during operation.
Cables of the PBPng (A) -HF brand are intended for group installation in rooms and cable structures in the presence of a risk of mechanical damage during operation.
Cables are recommended, first of all, for use at nuclear power plants, large thermal power plants, petrochemical facilities, in the subway, and on ships; in buildings and structures with a mass presence of people: concert halls and closed stadiums, theaters, airports and train stations; in rooms equipped with computer and microprocessor technology and other facilities that are subject to increased fire safety requirements.
Fire hazard class of cables according to NATIONAL QUALITY STANDARD 31565 P1b.8.1.2.1.
