Characteristics of Cable
 1.Max Long-time operating temperature of PVC insulated cable is 70°C,XLPE 90°C
 2.Installing temperature of cable should not be less than 0°C
 3.Max short-circuit temperature is:PVC not exceed 160°C,XLPE 250°C,Not more than5 Sec.
 4.Permitting bending radius cable: Not less than 10 D times (D:external diameter of cable)

Number of Cores & Nominal Cross-section Area

Installation:
1. The installation temperature should not over 20ºC, If the ambient temperature is lower than 0ºC, the cable should be preheated.
2. The bending radius of cable should not less than 8 times.
3. After installantion, the cable should with stand voltage test for 15min. 3.5kv D.C.

In air:
1.  As the single core cable laying in parallel, the distance between the cable’s center is 2 times (for cables which cross section area of conductor ≤185mm2) and
90mm (for cables which cross sectional area of conductor≥240mm2)
2. Ambient temperature: 30ºC
3. Max. temperature of conductor: 70ºC
4. Rating factors of current rating for ambient temperature:

Direct in ground:
1.  When the single core cables are installed separately, the distance between the cable’s center is 2 times of the cable diameter.
2.  Ambient temperature: 25ºC.
3.  Max. temperature of conductor: 70ºC.
4.  Soil thermour resistivity: 1.0ºC. m/w.
5.  Depth: 0.7m
6.  Rating factors under different ambient temp.:
