High Voltage XLPE insulated Power Cable Model

How to choose rated voltage

1.cable rated voltage shall be suitable for cable system operating conditions, with Uo / U (Um) KV representation.
Uo - conductor cable designed for ground or metal shield between the rated power frequency voltage ;
U - conductor cable designed rated power frequency voltage between ;
Um - the device can withstand the "highest system voltage" maximum.

2.Recommended 3 phase Uo Value

System Type A - such systems any phase conductor contact with earth or ground conductorthe system can be separated within 1min ;
System Type A- such systems include only a single fault conditions operating conditions , ground fault time should not exceed 1h, but in any case no longer than 8h, ground fault annual total duration does not exceed 125h;
System Type C- does not belong to A or B system type .
