XLPE Insulated Power Cable

Application: The cable is suitable to be installed in power transmission and distribution lines with the rated voltage ranging from 1 kV to 35kV
Standard: IEC 60502-1:2004, IEC 60502-2:2005

2.Maximum short circuit temperature of the cable conductor shall not exceed 250°C(duration not exceeding 5s);
3.Rated voltage of cables should fit the operating conditions of its system. Systems are classified into the following three categories:

Category A: In the event that one conductor contacts ground or any grounding conductor, it would be able to disconnect with the system within 1min;
Category B: In the event of single phase grounding fault, it could keep running for a short time. According to JB/T 8996, grounding fault duration should not exceed 1h. Although this standard allows a longer running time under faulty condition, it should be less than 8h in any circumstance. Its annual combined grounding fault duration should not exceed 125h;
Category C: This category comprises all systems which do not fall into category A or B.
