描述:
The cables are intended for transmission and distribution of electric power in stationary electrical installations at a nominal alternating voltage of 0.66 and 1 kV with a frequency of up to 100 Hz. The cables are intended for general industrial use and use at nuclear power plants (NPP) outside the containment area in NPP systems of class 2 according to the NP-001 classification. The cables are intended for use in electrical circuits that remain operational during a fire. PPGng(A)-FRHF is a cable with copper conductors, a thermal barrier of mica-containing tapes over the copper conductors, insulation and sheath of halogen-free polymer compositions.
概观:
Cables comply with the requirements of GOST 31996-2012.
Fire hazard class according to GOST 31565-2012: П1б.7.1.2.1.

Operating temperature range from minus 50 °C to +50 °C.
Relative air humidity at a temperature of +35 °C up to 98%.
Laying and installation of cables without preliminary heating is carried out at a temperature not lower than minus 15 °C.
Permissible heating temperature of the cores during operation:
- long-term - no more than +70 °C;
- in overload mode – no more than +90 °C;
- permissible for short circuit +250 °C (short circuit duration should not exceed 5 sec.);
- under conditions of non-ignition during a short circuit, no more than +400 °C.
Test voltage at 50 Hz:
- for voltage 0.66 kV - 3 kV;
- for voltage of 1 kV - 3.5 kV;
The electrical resistance of current-carrying cores, recalculated for 1 km of cable length and a temperature of +20 °C, complies with GOST 22483-2012.
Minimum bending radius for gasket and installation:
- single-core cables - 10 cable diameters;
- multi-core cables - 7.5 cable diameters;
Smoke formation during combustion and smoldering does not lead to a decrease in light transmittance in the test chamber by more than 40%.
The value of the equivalent toxicity index of cable combustion products is no more than 40 g/ m3 .
The amount of halogen acid gases released during combustion and smoldering of cable insulation and sheath materials, calculated as HCl, is no more than 5.0 mg/g.
Cables do not spread combustion when laid in groups according to category A.
Fire resistance not less than 180 minutes.
Cables in the "T" version are resistant to mold.
The construction length of cables is specified when ordering.
The warranty period is 5 years from the date of commissioning of the cable, but not later than 6 months from the date of manufacture;
Service life of at least 30 years.
