YJLV22-12/20kV
- 1、Product Model：YJLV22-12/20kV
- 2、Product Name：Aluminum conductor, XLPE insulation, steel tape armoured, PVC Sheath Power cable
- 3、Standard: GB/T 12706.1-2020
- 4、Application: This product is suitable for power supply, transmission and distribution lines with rated AC voltage U0/U of 26/35kV and below.
- 5、Characteristic：
- a) Normal operating Temperature: 70 ° C for PVC insulation and 90 ° C for cross-linked polyethylene insulation.
- b) The highest temperature of the cable conductor in the case of short circuit (the longest duration does not exceed 5 seconds) : polyvinyl chloride insulation - conductor cross-section ≤300mm2 is 160℃, conductor cross-section > 300mm2 is 140℃; Cross-linked PVC insulation at 250 ° C.
-
c) When the ambient temperature of the cable is not lower than 0 ° C, the minimum allowable bending radius is as follows： single core cable：Unarmoured is 20D，Armoured cable is 15 D
multi-core cable：Unarmoured is 15D，Armoured cable is 12D (D- The actual outer diameter of the cable) - d) Tensile：40×S（N） Note: S is the total cross-sectional area of the cable conductor.
