Application of PVC insulation sheathed electric cable
The PVC sheathed electric cable is used as power distribution and transimssion line at rated voltage 0.6/1kV which can be fixed.
The Laying Condition of Cables
Installation of electric cable
1. The installation temperaure should not over 20C, if the ambient temperature is lower than 0℃, the cable should be preheated.
2. The bending radius of cable should not less than 8 times.
3. After installation, the cable should withstand voltage test for 15min.3.5kv d.c.
4. As the single core cable laying inparallel, the distance between the cable: center is 2 times ( for cables, which cross sectional area of conductor 185mm2 )and 90 mm,(for cables, which cross sectional
area of conductor 240m㎡)
5. Ambient temperature:30 ℃
6. Max.temperature of conductor:70℃.
7. Rating factors of current rating for ambient temperature:
8. When the single core cables are installed separately, the distance between the cable: center is 2 times
of the cable diameter.
9. Ambient temperature: 25 ℃
10. Max.temperature of conductor:70℃
11. Soil thermour resistivity: 1.0℃ m/W
12. Depth:0.7 m.
13. Rating factors under different ambient temperature:
| Air temperature | 15℃ | 20℃ | 25℃ | 30℃ | 35℃ | 40℃ | 45℃ |
| Rating factors in air | - | 1.12 | 1.06 | - | 0.94 | 0.87 | 0.79 |
| Rating factors in soil | 1.11 | 1.05 | - | 0.94 | 0.88 | - | - |
