PRODUCT
YJLV62 high voltage cable
1. product standards:
This product is produced according to GB/T12706 "Rated voltage 1kV ~ 35kV extruded insulated power cable and accessories" standard, and can also be produced according to the needs of users according to the International Electrotechnical Commission recommended standards IEC, British standards, German standards and US standards.
2. the scope of application:
This product is suitable for power distribution rated voltage 3.6/6kV ~ 26/35kV transmission and distribution lines for distribution of electrical energy.
3. the use of features:
· The power frequency rated voltage U0/U is 3.6/6kV~26/35kV.
· The maximum allowable operating temperature of the cable conductor: 90 °C.
• The maximum temperature of the cable conductor does not exceed 250 °C in the event of a short circuit (maximum of 5 s).
· The ambient temperature should not be lower than 0 °C when laying cables.
· Cable bending diameter: The three-core cable is not less than 15 times the outer diameter of the cable; the single-core cable is not less than 20 times the outer diameter of the cable.
4. the choice of cable rated voltage:
• The rated voltage of the cable should be suitable for the operation of the cable system, expressed in U0/U(Um)kV.
U0- rated power frequency voltage between the conductor to ground or metal shield used for cable design;
· Rated power frequency voltage between conductors for U-cable design;
• The maximum value of the “maximum system voltage” that the Um-device can withstand.
