Power cables with insulation from cross-linked polyethylene for a voltage of 6, 10, 20, 35, 64/110 kV

Sector: Wires, Cables & Cable Assemblies
Price: Contract Price
Full Product Information:
Medium voltage power cables are designed for the transmission and distribution of electrical energy in fixed installations for a rated alternating voltage of 6, 10, 15, 20 and 35 kV with a nominal frequency of 50 Hz for networks with earthed and insulated neutral. Cables are designed for laying on complex sections of cable routes and are used when laying in ground, regardless of the degree of corrosive activity of soils and on routes with unrestricted difference in levels. It is allowed to lay the cables in the air, including installation in cable structures, provided that additional fire protection measures are provided, as well as in water (in non-navigable water bodies), while providing the measures that exclude mechanical damage to the cable. High voltage power cables are used for the transmission and distribution of electrical energy in three-phase networks for a rated alternating voltage of 64/110 kV with a nominal frequency of 50 Hz. Cables are designed for laying on complex sections of cable routes when laying in dry soils with humidity less than 14% on routes with unrestricted difference in levels, in case of single laying - in cable structures and industrial premises. Cables with “нг(А)-LS/ нг(В)-LS” index can be used for laying in explosion hazardous areas of classes B-Iб, B-Iг, B-II, B-IIа and on vertical sections of cable routes. Cables with “нг(A) -HF” index are used for fixed installation inside and outside the containment zone of NPP, as well as for laying in industrial and office premises, on production sites in which computers and other microprocessor devices are installed, in subways, residential and public buildings (cinemas, shops, educational and medical institutions). Cables with “нг(A)-FRLS/нг(A)-FRHF” index are used for electrical wiring of fire safety systems that function in case of fire (evacuation elevators, smoke removal systems, lighting of emergency exits, fire extinguishing pump power supply, etc.).
