Nominal voltage: 1.8/3 (3.6) kV 3.6/6 (7.2) kV 6/10 (12) kV 8.7/15 (17.5) kV 12/20 (24) kV 18/30 (36) kV Feature: XLPE insulated single core cable are applied for installation: 1. Indoors 2. Outdoors 3. Underground 4. Cable rack Construction: Conductor *Stranded compacted circular copper or aluminium conductors Conductor screen *Extruded semi conducting compound. Minimum thickness 0.5 mm and the maximum volume resistivity of 5000 ohm-cm at 20º C and 25000 ohm- cm at 90º 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 20º C and 25000 ohm- cm at 90º 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 Inner sheath *Extruded black PVC, capable for operating continuously maximum temperature of the cable Armouring *Double layers of galvanized steel tape tape applied helically with proper over laping over the inner sheath Outer sheath *Extruded red PVC, suitable for exposure to sunlight or other local atmospheric environments and for the operating temperature of the cable |
