Product Description

Description

N2XSEFGBY is a robust medium-voltage power cable designed for underground and fixed installations, particularly in environments that demand mechanical protection and EMI shielding. It features:

• Copper conductors for high conductivity

• XLPE insulation for thermal and dielectric strength

• Copper tape screen for field control and fault current return

• Galvanized steel flat wire armor (SWA) for mechanical protection

• PVC sheath for chemical and weather resistance

 

Applications

This cable is typically used in:

• MV distribution networks (rated 3.6-30 kV)

• Power stations and substations

• Industrial installations, refineries, and petrochemical sites

• Underground installations, direct burial or ducts

• Outdoor and indoor fixed installations where enhanced mechanical strength and electrical shielding are required

Advantages:

• Withstands mechanical stress and rodent damage

• Suitable for harmonically rich environments due to effective shielding

• Copper tape screen limits electromagnetic interference (EMI)

• SWA provides enhanced armor integrity compared to tape armor
