Power cables with copper and aluminium conductors, with plastic insulation, in a plastic cladding, hereinafter referred to as “cables”, intended for the transmission and distribution of electricity in stationary installations with a rated alternating voltage of 0.66; 1 and 3 kV with a nominal frequency of 50 Hz. The cables comply with GOST 31996. GOST 31996 meets international standard IEC 60502-1:2004.
The cables are intended for the needs of the national economy and are used at industrial and energy facilities. Cables in the “ng(A)-LS” design can be used at nuclear power plants outside the containment area in AC systems of classes 2, 3 and 4 according to the OPB 88/97 classifier (PNAE G-01-011) and at metro facilities.
Cables that do not spread flame when installed in groups can be used in explosive zones of classes 0, 1 and 2 according to GOST 30852.13-2002 (IEC 60079-14:1996).
The cables are seismically resistant to earthquakes with an intensity of 9 points according to MSK – 64 at an installation level above the zero mark of up to 35 m, seismic safety group 2 according to GOST 30546.1
Type of climatic modification UHL, placement categories 1 – 5 according to GOST 15150.
Warranty period: 5 years.
The cables are designed for use in alternating voltage electrical networks with a grounded or insulated neutral. The duration of operation in networks with an isolated neutral in the mode of a single-phase short circuit to earth does not exceed 8 hours, and the total duration of operation in the mode of a single-phase short circuit to earth does not exceed 125 hours in 12 months.
The maximum network voltage at which cables can be operated Um is 1.2U.
The cables are allowed to be used in direct current electrical networks at voltage values 2.4 times higher than Uо (where Uо is the rated voltage between the core and the screen, kV).
Cables can be laid without limiting the difference in levels along the laying route, including in vertical sections.
All cables, except for cold-resistant cables with an outer sheath or protective hose made of polyvinyl chloride plastic or a halogen-free polymer composition, can be laid without preheating at a temperature not lower than minus 15 ° C.
Cold-resistant cables with an outer sheath or protective hose made of polyvinyl chloride plastic or a halogen-free polymer composition can be laid without preheating at a temperature not lower than minus 30 °C.
Cables with cross-linked polyethylene insulation or cables with a protective polyethylene hose can be laid without preheating at a temperature not lower than minus 20 °C.
The minimum bending radius during installation must correspond to that indicated in table 1.
