Application: The 33kV MV Power Cable Copper Conductor XLPE Insulation 185mm Cable is suitable to be installed in transmission and distribution lines.
Standard: IEC, BS, ASTM, AS/NZS, IS and other standards as customers' required.
1) Max. operating temp. of the cable conductor is 90˚C.
2) Max. short circuit temp. of the cables conductor shall not exceed 250˚C.(max. duration not exceed 5s)
3) There are three kinds of rated voltage (U0) according to the ground fault duration, see the following table.
Type A: when any phrase conductor of this system connected to ground or earthed conductor, it can be separated with the system within 1minute.
Type B: when single phrase grounded of this system,it can run short time. The grounded time should not exceed 1 hour. cables under this system should not run over 8 hours In Soiled fault situation and the total continue fault grounded time of one year should not exceed 125 hours.
Type C: included all systems excluded in A & B.
4) When laying the cables at the ambient temp. of 0˚C and above, there is no need to pre-heat.
