Single Core Cable Type N2XSY, NA2XSY
SINGLE CORE CABLE
COPPER OR ALUMINIUM CONDUCTOR,
COPPER WIRES SCREENED AND PVC SHEATHED
Type N2XSY, NA2XSY
XLPE insulated single core cables are applied for installation indoors, outdoors, underground and cable rack.
Stranded compacted circular copper or aluminum 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.
Extruded Semi-conducting compound. Minimum thickness 0.5 mm and the maximum volume resistivity of 5000 ohm-an at 20° C and 25000 ohm-cm at 90° C.
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.
3.6/6 ( 7.2 ) kV
6/10 ( 12 ) kV
8.7/15 ( 17.5 ) kV

Table 2 . Minimum Total Cross Section Of Metallic 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 exclude 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 of moisture or water.
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 swell up under the influence of moisture or water.
Extruded red PVC, suitable tar exposure to sun-light or other local atmospheric environments and for the operating temperature of the cable.
