Description
XLPE-insulated power cables for rated voltage 110kV should perform the rules of XLPE-insulated Power
Cable for Cable for Rated Voltage 110kV and its attachments in GB/T 11017-2002, which is equal to The
Test Methods and Requirements of Extruded Insulation Power Cables for Voltage 30kV up to 150kV in IEC 60840:1999.
XLPE-insulated power cables for rated voltage 220kV should perform the rules of XLPE-insulated Power
Cable for Cable for Rated Voltage 220kV and its attachments in GB/T 18890-2002, which is equal to The
Test Methods and Requirements of Extruded Insulation Power Cables for Voltage 150kV up to 500kV in IEC 62067:2001.
XLPE-insulated power cables for rated voltage 500kV should perform the rules of XLPE-insulated Power
Cable for Cable for Rated Voltage 220kV and its attachments in GB/T 22078-2008, which is equal to The
Test Methods and Requirements of Extruded Insulation Power Cables for Voltage 150kV up to 500kV in IEC 62067:2006.
XLPE-insulated power cables for rated voltage 66kV should perform The Test Methods and Requirements
of Extruded Insulation Power Cables for Voltage 30kV up to 150kV in IEC 60840:1999.
Main Performance
1. The rated voltage U0/U of cables:38/66kV, 48/66kV, max. voltage Um=72.5kV;
64/110kV, max. voltage Um=126kV;
127/220kV, max voltage Um=252kV;
290/500kV, max voltage Um=550kV;
2. permissible long-term working temperature of cable conductor:90℃;
3. When the cable confronts short circuit within 5 seconds, the highest temperature of conductor should
not exceed 250℃. When there exits line joints, the temperature of tin soldering ones should not exceed
120℃, the temperature of crimping ones should not exceed 150℃, and the temperature of electric or
gas welding should not exceed 250℃；
4. When laying, the permissible bending radius should exceed 25 times of the out diameter of the cables.
After laying, the permissible bending radius should exceed 23 times of the out diameter of the cables.
1. When laying, ambient temperature≥0℃(when the cable has to be laid under the ambient temperature
below 0℃,it is necessary to preheat the cable above 0℃)
2. When laying, the cable is not limited by disparity with the satisfaction of mechanical pressure, but it is
not permissible to lay the cable in the iron pipe, nor the circular iron materials around fixed cables.
