Common information
Area of application:
Area of application: N2XSY, NA2XSY, N2XSY-LS, NA2XSY-LS, N2XS2Y, NA2XS2Y, N2XS2Y, NA2XS2Y, N2XS(F)2Y, NA2XS(F)2Y, N2XS(FL)2Y, NA2XS(FL)2Y, N2XS(FL)2Y, NA2XS(FL)2Y type power cables are used during stationary installation specified for distribution and transmission of electric power. Cables are used in areas without external mechanical effects, renches and underground.
N2XS(F)2Y, NA2XS(F)2Y, N2XS(FL)2Y, NA2XS(FL)2Y type cables are used under high humidity grounds, constantly humid and flooded right-of-ways with complex configuration.
N2XSSEB2Y, NA2XSSEB2Y type cables are used in right-of-ways with complicated configuration, since they are protected from external mechanical effects.
