N2XSH Medium Voltage Cable XLPE-insulated Longitudinally Watertight LSZH Cable
APPLICATION
The single-core cables flame retardant with insulation of
cross-linked polyethylene (XLPE) are designed for transfer and
distribution of electrical power with nominal voltage Uo/U 6/10;
12/20 kV and frequency 50 Hz. The cables are manufactured with
sheaths of halogen free flame retardant materials.
They are suitable for use in distribution installations, electric
power stations and substations for fixed indoor assembly in cable
ducts and conduits, over shelves and grilles. They should not be
laid directly underground or in water.
The cables with halogen free materials are with low halogen free
smoke emission and corrosivity. The cables should not be laid in or
near nuclear stations.
