YJSV (N2XSY) Single-core  6/10kV 8.7/15kV 12/20kV 18/30kV

CU / XLPE / CWS / PVC

(Copper conductor, XLPE insulated, Copper Wire screened, PVC sheathed)

Application:

Medium voltage power cable for static application in ground, within and outside facilities, outdoor, in cable canals, in water, in conditions where cables are not exposed to heavier mechanical stress and tensile strain. Due to its very low factor of dielectric loss, which remains constant over its entire operating lifetime, and owing to excellent insulation property of XLPE-material, firmly longitudinally spliced with conductor screen and insulation screen of semi-conductive material (extruded in one process), the cable has a high operating reliability. Used in transformer stations, electric power plants and industrial plants.

Construction ：

• 1) Conductor : Copper ,Class 1 or Class 2,solid or stranded Circular conductors  
• 2) Conductor screen: Non-metallic，semi-conducting compound
• 3) Insulation: Cross-linked polyethylene XLPE
• 4) Insulation screen: Non-metallic，semi-conducting compound
• 5) Metallic screen: Copper wire and copper tape
• 6) Oversheath: Polyvinyl chloride PVC

SPECIFICATIONS:

IEC 60228 Conductors of insulate cables

IEC 60502-2 Power cables with extruded insulation and their accessories for rated voltages from 1 kV(Um=1.2kV) up to 30kV(Um=36kV) - Part 2:Cables for rated voltages of 6 kV(Um=7.2kV) and 30 kV(Um=36kV)
