Product Detail

20.3/35 kV or 20.8/36 kV XLPE Insulated, Longitudinally Sealed Single Core Cables with Aluminum Conductor

Code

NA2XS(F)2Y, AL/XLPE/SCWBT/CWS/WBT/PE

Standards

HD 620 S2, TSEK

 

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 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
