CONSTRUCTION for XLPE/PVC 4 Core Cable

1).Conductor
Stranded compacted circular copper or aluminium conductors. All internal interstices of trie conductor rilled with water blocking compound which is specified to prevent ingress of water through conductor during storage, handling, installation and operating of the cable.

2)Conductor Screen
Extruded Semi-conducting compound. Minimum thickness 0.5 mm and the maximum volume resistivity of 5000 ohm-cn at 20° C and 25000 ohm-cm at 90° C.

3).Insulation
Extruded XLPE with high degree of cross-linking, free from contaminants, air voids and heat resistant by dry cured process.

The nominal thickness as shown in table 1.

Insulation Screen for XLPE/PVC  4 Core Cable
Extruded Semi-conducting compound. Minimum thickness 0.5 mm and the maximum volume resistivity of 5000 ohm-cm at 20°C and 25000 ohm-cm at WC The screen is tightly fitted to insulation to exdude all air voids and can be easily hand stripped on site.

Armouring for XLPE/PVC 4 Core Cable  
Galvanized flat steel wires with thickness 8.0 mm wrap helically over the surface of inner sheath minimum 90%. And galvanized Steel tape with nominal thickness 0.3 mm wrap helically minimum 50% cover the surface of the flat wires.

Outer Sheath for XLPE/PVC  4 Core Cable
Extruded red PVC, suitable tar exposure to sun-light or other local atmospheric environments and for the operating temperature of the cable.
