Voltage designation
The rated voltage of the cable for a given application shall be suitable for the operating conditions in the system in which the cable is used , and is expressed in the form Uo/U(Um)kv .
Where:
Uo—The rated power-frequency voltage between conductor and screen or metallic-sheath , for which the cable designed;
U — The rated power –frequency voltage between conductors , for which the cable designed ;
Um—The maximum value of the “highest system voltage “ for which the equipment may be operated.
