This product according to GB/T12706 the rated voltage 1 kv ~ 35 kv extrusion insulated power cables and accessories, standard production, at the same time can also be based on user needs according to the international standard of IEC, English, German and American standard production.
This product is suitable for rated power-frequency voltage up to 3.6/6 kv ~ 26/35 kv power transmission and distribution lines with.
Rated power-frequency voltage U0 / U for 3.6/6 kv ~ 26/35 kv.
The allowable working temperature, cable conductor: 90 ℃.
, when short circuit (the longest not more than 5 s) cable conductor does not exceed the highest temperature of 250 ℃.
, when cable laying temperature should not below 0 ℃.
The bending diameter: 3 core cable is not less than 15 times the cable diameter; Single core cable should not less than 20 times the cable diameter.
The selection of rated voltage
, the rated voltage of the cable shall be suitable for the operation condition of the cable system, using U0 / U (Um) kV said.
U0 - cable design, use of the conductor to ground or between metal shielding rated power frequency voltage;
U - cable design with rated power frequency voltage between conductors;
Um - equipment can withstand a maximum of the "highest system voltage".
A system ─ ─ the system phase conductor and earth and the grounding conductor, separated from system within 1 min;
B system ─ ─ the class system is single-phase earth fault in a short run, but in any case the longest run time does not exceed 8 h, ground fault total duration of not more than 125 h every year;
C system ─ ─ don't belong to the class A and class B system.
