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.
