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
