Product Detail

40/69 kV XLPE Insulated, Radial and Longitudinally Sealed, Single Core Cables with Aluminum Conductor

Code

NA2XS(FL)2Y, AL/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 aluminum 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

NOTE                        : Current carrying capacities are valid under the following conditions.

In ground                 : 200C; buried in 70 cm depth; soil thermal resistivity 1 K.m/W; load factor 0.7

In Air                        : 300C; load factor 1.0

***                          : Flat formation; clearance between cables in air = 1 x cable outer diameter; in ground = 7cm

***                           : Trefoil formation

Number of System    : 1
