3 Core Copper Conductor XLPE Insulated Power Cable


Construction:
1) conductor:
  Conductor:Stranded compacted circular copper or aluminium conductors according to IEC 60228 
class 2 / VDE 0276 class 2. VDE 0295 HD 383. All internal interstices of the conductor are filled with water
 blocking 
compound to prevent ingress of water through conductor during storage, handing, installation and 
operating 
of the cable
 
3 Core Copper Conductor XLPE Insulated Power Cable

2)   Conductor Screen:
The conductor screen consists of an extruded layer of non metallic, semi-conducting compound firmly bonded to the insulation to exclude all air voids. The screen has a 
minimum thickness
 of 0.3mm and the maximum volume resistivity of 500 Ohm-m at 90°C.

3) Insulation:
Insulation is of extruded XLPE compound type 2XI1 according to DIN VDE 0207 part 22 and HD 620.1 
with high 
degree of cross-linking, free from contaminants, air voids and heat resistant by dry cured process.

4)Insulation Screen:
The insulation screen consists of extruded non metallic, semi-conducting compound extruded over the insulation. The extruded semi-conducting layer shall consist of bonded or cold strippable semi-conducting compound capable of removal for jointing or terminating. The minimum thickness is 0.3mm 
and the
 maximum volume resistivity of 500 Ohmm at 90°C. The screen is tightly fitted to the insulation to
 exclude all air 
voids and can be easily hand stripped on site.

5)Conducting Water Blocking Layer:The insulation screen may be covered by semi- conductive water 
blocking 
tape which will swell up under the influence of moisture of water to ensure longitudinal watertightness.
 
6)Metallic Screen: Copper tape screen or copper wire screen (CTS / CWS )
Copper wires are applied over the conducting water blocking layer with a minimum diameter of 0.5mm.
 And over the copper wires, copper tape with minimum thickness of 0.1mm is applied helically with 
overlap. Total cross section of metallic screen layer is shown in table 2. The screen can withstand of
 fault current to earth of 1000 A for one second at maximum temperature of 160°C. Minimum cross
 section of concentric conductor is according to DIN VDE 0273 & 0276 as shown.
 
7)Separator / Water Blocking Layer:
The metallic screen may be covered by non-conducting water blocking tape which will swell up under the influence of moisture of water to ensure
 longitudinal 
watertightness.

8)Separation Sheath (for armoured cable):
The separation sheath comprises a layer of extruded PVC, PE or LSZH, applied under the armour. 
 
9)Armour(for armoured cable): The armour consists of:  Single Core: Aluminium Wire Armoured (AWA)
Multi-core: Steel Wire Armoured (SWA) or Steel Tape Armoured (STA) 
(1) Double layers of galvanized steel tape are applied helically with proper inner overlapping over an 
extruded 
separation sheath. 
 
(2) Galvanized flat steel wires with thickness of 0.8 mm are applied helically over the surface of inner 
sheath with 
minimum of 90% coverage. And galvanized Steel tape with nominal thickness of 0.3 mm is applied
 helically with 50% coverage to cover the surface of the flat wires.
 
10)Outer Sheath:
Overall sheath comprises a layer of extruded PE compound DMP2 according to HD620.1 and 2YM3 type
 to DIN
