Overhead Twisted Cable NFA2XSY-T Construction
Conductor
Stranded compacted circular alumunium conductors. All internal interstices of three conductor filled 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-cm at 20°C and 25000 ohm-cm at 90°C.
Insulation
Extruded XLPE with high degree of cross-linking, free form contaminants, air voids and heat resistant by dry cured process.
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 90°C. The screen is tightly fitted to insulation to exclude all air void and can be easily hand stripped on site.
Metallic Screen
Copper tape applied over the Insulation Screen copper tape with minimum thickness 0.1 mm and maximum 0.3 mm.
Outer Sheath
Extruded black PVC, suitable for exposure to sun-light or other local atmospheric environments and for the operating temperature of the cable.
