SINGLE CORE CABLE

  • COPPER OR ALUMINIUM CONDUCTOR,
  • XLPE INSULATED,
  • COPPER WIRES SCREENED AND PVC SHEATHED
  • Type N2XCY, NA2XCY

Feature
XLPE insulated single core cables are applied for installation indoors, outdoors, underground and cable rack.

CONSTRUCTION

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.

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.

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.

Table 1. Insulation Thickness

Insulation Screen
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.

Conduction Water Blocking Layer
Semi-conductive water blocking tape provided over the insulation screen which will swell up under the influence ofmoisture or water.

Metallic Screen
Copper wires applied over the conducting water blocking layer. Minimum cross section of concentric conductor as shown in table 2. Copper tape with minimum thickness 0.1 mm and maximum 0.3mm applied over copper wires.

Water Blocking Layer
Non-conducting water blocking tape provided the metallic screen which will swellup under ihe influence of moisture or water.

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