Product Detail
20.3/35 kV or 20.8/36 kV XLPE Insulated, Radial and Longitudinally Sealed Single Core Cables with Aluminum Conductor
|
Code NA2XS(FL)2Y, AL/XLPE/CWS/LW/PE Standards IEC 60502-2, VDE 0276-620, BS 7870 - 4.10
|
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 aluminum conductor 2. Inner
semi-conductive layer 3. XLPE
insulation 4. Outer
semi-conductive layer 5.
Semi-conductive swelling tape 6. Copper
screen 7. Swellable
tape 8. PE coated aluminum foil 9. PE outer jacket |
