Code
N2XS(F)2Y, CU/XLPE/LW/CWS/LW/PE

Standards
TS IEC 60502, VDE 276, BS 7870

Technical Data
Max. operating temperature : 90 ° C
Max. short circuit temperature: 250 ° C (max. 5 sec.)
Rated voltage : 12/20 kV - 12.7/22 kV
Min. bending radius :15xD
D : Cable outer diameter

Application
These are cables with low dielectric losses used in energy networks with sudden load changes. Laid in residential or industrial areas, underground or in ducts. If the cable gets water inside due to the mechanical demages, swellable tapes prevent the movement of the water inside the cable.

Construction
1. Stranded copper conductor.
2. Inner semi-conductive layer.
3. XLPE insulation
4. Outer semi-conductive layer
5. Semi-conductive swellable tape
6. Copper wire screen
7. Swellable tape
8. PE outer jacket
