Selection of Rated Voltage of Cable:


If the rated voltage of cable is appropriate with the operation-state of cable-linking system, “U0/U (Um)” are indicated, all of them are effective values with application unit “kV”.
U0– rated power frequency voltage between ground cable conductor and metal screening material;
U- rated power frequency voltage between conductors of cable;
Um- the biggest value of the highest system-voltage of working cable.

Three-phase system-used rated voltage of cable as follows:

Note: Category-I------ used for single-phase ground connection, and the fault time of system is not over 1min each time and the longest one not over 8 hours, the total fault occurring hours of the system not over 125 hours every year.
Category-II------used for the system with longer time of ground connection fault and also adopted for the places required for relative high insulation performance of cable.
