1.1 Rated voltage
This series of the rated voltage of the cable is expressed as U0 / U (Um) form, including:
"U0" designed for the cable conductor to ground or between metal shielding rated power-frequency voltage up to;
"U" for cable design with rated power-frequency voltage between conductors;
"Um" for the equipment can withstand a maximum of "highest system voltage.
The series cable is mainly is divided into the following three categories:
1.2 Rated voltage of 1 kV and 3 kV extruded power cable and the U0 / U (Um), respectively (1.2 kV) and including 0.6/1 kV 1.8/3 kV (3.6 kV) which mainly U0 / U (Um) = 0.6/1 kV (1.2 kV) is the most commonly used;
1.3 Rated voltage of 6 kV to 30 kV electric power cable, extruded and U0 / U (Um) correspond to the 3.6/6 kV (7.2 kV), 6/6 kV (7.2 kV), 6/10 kV (12 kV), 8.7/10 kV (12 kV), 8.7/15 kV (17.5 kV), 12/20 kV (24 kV), 18/30 kV (36 kV) seven levels, of which U0 / U (Um) = 8.7/15 kV (17.5 kV) is the most commonly used;
1.4 Rated voltage of 35 kV electric power cable, extruded and U0 / U (Um) respectively 21/35 kV (40.5 kV) and 26/35 kV (40.5 kV), of which U0 / U (Um) = 26/35 kV (40.5 kV) is most commonly used.
