3.6/6kV~26/35kV Cross-Linked

3.6/6kV~26/35kV Cross-Linked
Polyethylene Insulated Power Cable

Uses:
The product is suitable to be used for electrical distribution and supply of transmission line with power frequency rated voltage 3.6/6kV~26/35kV. And 900C is the allowable highest long-term operating temperature of cable conductor; the highest temperature of cable conductor can't be above 2500C when short circuit occurs.

Selection of Rated Voltage of Cable:

If the rated voltage of cable is appropriate for 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:

U	Um	U0
U	Um	Category-I Cable	Category-II Cable
3	3.6	1.8	3.6
6	7.2	3.6	6
10	12	6	8.7
15	17.5	8.7	12
20	24	12	18
35	42	21	26

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.
