Product Detail
40/69 kV XLPE Insulated, Radial and Longitudinally Sealed, Single Core Cables with Copper Conductor
|
Code N2XS(FL)2Y,
CU/XLPE/LW/CWS/LW/PE Standards VDE 0276-632, IEC 60840 |
Application Characterized with low
dielectric loss. Used in energy networks where load may change suddenly. Laid
in residential or industrial areas, and underground in ducts. In case water
sneaks into cable due to any mechanical damage, swellable tape prevents
penetration of water inside the cable. Construction 1. Stranded copper conductors 2. Inner
semi-conductive layer 3. XLPE
insulation 4. Outer
semi-conductive layer 5.
Semi-conductive swelling tape 6. Copper
screen 7. Semi-conductive
swelling tape 8. PE coated
aluminum foil 9. PE outer jacket |
