1、Description
The 66 kV to 500 kV high voltage cable is the key equipment used in the power system for long distance power transmission, with high voltage, large capacity and high reliability.
2、Construction
Conductor
Copper conductor, stranded, cross-sections of 1000 sqmm and above segmented conform to IEC60228, optionally with longitudinal water barrier.
Conductor Screen
Inner semi-conductive layer, firmly bonded to the XLPE insulation
Insulation
Super-clean XLPE
Insulation Screen
Outer semi-conductive layer, firmly bonded to the XLPE insulation
Metal Screen
·Corrugated aluminum (or copper) sheath, lead sheath and aluminum-polymer laminated sheath can be applied as metallic sheath of the HV power cable. A layer of annealed copper wires can be added as a metallic screen to meet the short-circuit current requirements during ground faults. Copper wire screen with semi-conductive swelling tapes as longitudinal water barrier
Outer Sheath
PE /PVC over sheath conform to IEC60840
3、Application
In urban power grids, high-voltage cables can be utilized to connect different substations, achieving extensive coverage and high-reliability power supply within the urban area. Through transmission lines of this voltage level, the electrical energy generated by power plants can be efficiently transported to various locations, ensuring that the normal power demands of the city are met.
Note: Cables complying with IEC62067.HD632 and customer’s specification are available upon request.
