6,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 of 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:
Urn-The maximum value of the "hight system voltage " for which the equipment may he operated.
7,Rated voltaged of cable applied in three phrase system are given in table
