Description

Construction Details

Conductor: Annealed Plain Copper or Aluminium Compacted Round Stranded Conductors to carry Current and withstand Pulling Stresses During Cable Laying. Conductors Complying with IEC 60228.
Inner Semi-Conducting Layer: Extruded Layer of Semi-Conducting Screen over Conductor to Smooth the Electric
Screen: Field at the Conductor and Firmly Bonded to the Insulation to exclude all air voids ,and Prevent Concentration of electric field of the interface between the Insulation and the Inner Semi-Conductor. Semi-Conducting Compound Complying with IEC 60502-2
Insulation: The Insulation of XLPE ( Cross-Linked Polyethylene ) Rated Voltage, Lightning Overoltage, Switching Overvoltage, and Withstand the Various Voltage Field Stress During the Cable Service Life as per IEC 60502-2
Core Semi-Conducting: Extruded Layer of Semi-Conducting Screen over the Insulation . The Screen is Tightly

Armour & Sheath

Metallic Screen: The Metallic Screen Shall Consist of Copper Tape. The Metallic Layer may be applied over the Individual Cores. Metallic Screen Provide no Electric Field outer side of the Cable
